Compared to the complexity of purchasing a new graphics card or swapping out your motherboard purchasing a USB hub is definitely a simple purchase; but that doesn’t mean you should just grab the first one off the shelf at your local electronics store. There is an enormous discrepancy between build quality, features, and even safety between the different models. Read on as we show you what you need to get the best results and find the hub that fits your needs.
What’s a USB Hub and Why Do I Want One?
Although we’ve grown well beyond the days of desktop computers arriving equipped with only a few USB ports (it’s not uncommon for computers to now have 4-6+ on the back and 2-4 on the front of the case), most of us have also managed to acquire many USB-based devices. It’s not unusual for a home user to have a USB-based keyboard, mouse, printer, scanner, and memory card readers, as well as charging/syncing cables for iPods, phones, e-book readers and other portable devices. Even though you might reuse the same mini USB cable for a few devices, it’s all too easy to tie up a lot of USB ports rather quickly. Factor in the location of your physical computer relative to your workspace and it can quickly become impossible (because the ports are full) or inconvenient (because the computer is located under your desk) to plug in more devices. As far as laptop users are concerned, well they can just forget it when it comes to an abundance or ports. We all want super slim and super light laptops which leave little room for an armada of USB ports. One of our favorite ultra-slim notebooks we use for work-from-coffee-shop jaunts has a mere two ports.
So where does that leave you, the over-deviced and under-ported computer user? In need of a USB hub. If you’re not familiar with USB hubs, don’t worry. A USB hub is to USB devices as a power strip is to electrical devices: you use a hub to split the capability of one USB port on your computer among many devices just as you use a power strip to split the electrical power from a single outlet in your home or office among multiple electrical devices.
Just like power strips aren’t all created equal (you wouldn’t plug your $10,000 home theater system into a $5 no-name power strip from Wal-Mart, after all), all USB hubs aren’t created equal. Not only do you need to pay attention to features and specifications (despite how simple a USB hub might appear at first glance) you also need to be aware of the existing hardware on your computer (be it a desktop or laptop) in order to get the best performance out of your the hub.
Let’s take a look at a few different USB hubs and use them to highlight why we would select different hubs for different applications as well as the benefits and shortcomings of each.
First, Meet the Models
Just like with the HTG to External Battery Packs, we’re showcasing devices we actually use and endorse. For this guide we’ll be using the HooToo HT-UH010 7-Port USB 3.0 Hub and the LOFTEK 7-Port USB 3.0 Hub. In addition we’ll also be referencing a few other USB hubs which were unavailable for a photo session on account of being out and about in the field with other writers and staff members.
We’ve been quite pleased with both models but, rather than listing off all the reasons why first, let’s dig into the types of features a good USB hub has so you can understand exactly why we’re pleased with the USB hubs in question. You’ll learn how to pick a good USB hub for your own needs in the process.
Spend Cash; Acquire Safety
Before we delve into the features that are obvious (case design, number of ports, etc.) let’s talk about the most important feature that isn’t readily apparent to end user: internal construction and safety measures.
The two USB hubs we’re showcasing in this guide aren’t the most expensive on the market but they aren’t Big Mac meal cheap, either. The HooToo will run you around $40 and the LOFTEK will run you around $45. Even small but high-quality laptop USB adapters run around $15 or so. You can buy both desktop and laptop USB adapters for very cheap; it’s easy to eBay a powered adapter for around $10 or less.
We’d strongly caution you against doing so. In the best-case scenario, you’ll end up with a device that’s a knock-off in name but possibly built to similar specs (and maybe even at the same factory) as the brand name. In the middle-of-the-road scenario you’ll end up with a poorly wired, insulated, and protected device that could possibly lead to one or more of your expensive attached devices getting fried thanks to poor design and construction. In the worst-case scenario where all the stars align against you and both the safety features in the USB hub fail you along with other safety features in either your laptop, the USB hub’s power brick, or other failures, you can end up like this poor woman in Australia: a cheap USB phone charger had a catastrophic failure that killed her.
That’s obviously an extreme case, but it highlights how buying the cheapest peripherals and chargers comes with an inherent risk. If a sub-spec power transformer blows out and starts the back of your desk on fire while you’re at work that extra $20 you could have spent on a higher quality device will be a drop in the bucket compared to dealing with even a small house fire.
Lightning strike probability of a bad USB port killing you aside, you’re typically purchasing better build quality when you spend a little extra. We tested both the HooToo and the LOFTEK with all the USB devices we could throw at them doing all sort of bus/power taxing things like multiple USB hard drive read/writes concurrently, ejecting and remounting other devices during those processes, pulling mobile data through a USB dongle, and so forth all without a single hitch. Flakey hubs are frustrating, but you can easily avoid data drops and safety hazards by picking a high quality and highly rated hub.
Buy the Most Current Standard
The USB standard has gone through several iterations since its public release back in 1996. Each iteration has introduced new features, the most notable of which is increased transfer speeds. Other features include battery charging specifications (introduced in USB 2.0 and upgraded in 3.0), better data handling for concurrent connections, and such.
Although it’s quite rare to find a USB 1.0 hub anywhere these days (unless you discover it on the dusty shelves of a small town electronics store), there are still plenty of USB 2.0 hubs floating around. While the capability of a USB 2.0 hub might be just fine for your present needs the price difference between a quality USB 2.0 and USB 3.0 hub is negligible and there’s very little reason to buy a USB hub based on 2000-era speeds and technology when you can get a USB 3.0 hub for a little more. A year or two from now when you’re using that hub for more than a few lightweight peripherals and wish to plug a USB 3.0 external hard drive (or two) into it, you’ll be happy you’re not dragging at USB 2.0 transfer speeds. Even when buying a hub for an old computer that doesn’t even support USB 3.0, you should strongly consider getting the newer standard. After all, that old laptop could kick the bucket any day leaving you with a hub to repurpose for a new project (or to move onto your new, definitely has USB 3.0 ports computer).
If you’re reading this guide years down the road and the new standard is USB 4.0, the same rule applies. Don’t buy old technology when a few extra bucks will give you better speeds and more features.

Unless Ultra-Portability Is Critical, Buy Powered
Aside from data-speed bottlenecks introduced by using old USB hubs on modern USB 3.0 ports, the biggest shortcoming you can introduce to your USB hub setup is a lack of power. USB hubs come in two flavors, in regard to power, bus-powered (wherein the hub draws power from the host computer via the USB bus/port it is connected to) and self-powered (wherein the USB tether to the computer is exclusively for data and the actual power for the hub and attached devices is pulled from a separate power pack). Although not as common, some USB hubs are dynamic-powered and feature a circuit which can detect whether or not the hub is currently bus-powered or has been hooked up to a transformer to become self-powered and will adjust itself accordingly.

If you’re using a little USB travel hub, like the Sabrent 4-Port USB 3.0 Hub, you’re limited to the maximum amount of power the USB port the hub is attached to can provide. This is more than fine for a simple setup like adding an external keyboard and mouse to your laptop to create a more comfortable workstation, but once you start adding more demanding devices into the mix like USB hard drives and the like the lack of power quickly becomes a problem.
In such a case the problem is completely resolved by using a powered USB hub. Each port on the USB hub will receive full USB-standard power with no dips in power or devices disconnecting for want of a stable connection. Especially for projects like adding peripherals to the Raspberry Pi microcomputer, a powered USB hub is mission critical as the host device just can’t crank out enough juice for a bevy of attached devices.
Both of the HootToo and LOFTEK feature separate power supplies that offer a nice stable source of power for all ports.
The More Ports the Merrier
Again, unless ultra portability is critical, bigger is better. If you need four extra USB ports on your machine today, it’s silly to buy a 4-port USB hub. There’s bound to be another device around the corner you need to add in. Especially if you’re purchasing the hub for a desktop computer where portability isn’t even a factor (and you can easily tuck the USB hub out of sight regardless of how big it might be), it simply makes sense to pay a few extra bucks for a few more ports. Doing so is certainly more economical and convenient than buying a bigger hub next year or adding a USB expansion card to your computer.
In addition, pay attention to how the ports are oriented on the hub. The two units featured here have two totally different approaches to port arrangement. The HooToo features a vertical-orientation design reminiscent of an electrical power strip. The LOFTIS features a side-out arrangement more common in smaller travel hubs. All things equal (number of ports, external power, etc.) the form factor can make or break a purchase depending on how you want to place your USB hub. If you want a strip you can tuck behind your monitor shelf or computer tower, the HooToo design makes sense. If you want a hub that you could, say, adhere to the bottom of your monitor shelf so there were always a few ports facing out for flash drives and infrequently used peripherals, the LOFTIS design is more practical.
Power-Only Ports Are Very Convenient
Although they’re absolutely not a necessity, many larger USB hubs come with charging ports that are quite convenient. USB data port standards limit the output of USB data port power transfer to a maximum of 500 mA (an amount that is stepped up in increments of 100 mA depending on how much power the attached device requires). While that’s fine for sustaining data transfer or powering a device, it’s not so great for charging a power hungry portable device such as an iPad or smartphone.
Premium USB hubs often include, as our two models do, discrete non-data charging ports that provide 1A power (twice the amount of a standard USB data port, like that of a USB phone charger) and 2.1A (a little over four times the amount of a standard USB port, like that of a tablet or large peripheral charger). Not only does this add a big dose of convenience to your user experience but it also frees up electrical outlets as you’re not plugging in individual chargers for your devices.
One tip we’ll share (and born of our own frustrations) is that it’s easy to confuse the data-only/power-only ports when there are similar or identical free cables plugged into both. Our solution was to use all black cables for the data ports and to use white cables for the power ports to eliminate any “Why isn’t my Kindle mounting?” late night frustrations.
The only caveat we can offer in this section is to be sure you read the description carefully. If you’re looking for a 10-port hub, for example, make sure the description indicates that there are 10 data ports plus any charging ports you’d like (a poor or dishonest product description could leave you with an 8 data port/2 charging port hub instead).
Read the Fine Print for Minor but Appreciated Features
Once you get past the basics: solid (and safe) build construction, bus-powered/self-powered, and the number of ports you want, the rest of choices are largely aesthetic in nature or focused on small but appreciated details. Each of the units we showcased today features these kind of details.
The HooToo hub, for example, has tiny LED numbers beside each data-port on the strip. If a device is plugged in and has formed a data connection with the host computer the light turns on. If the cable plugged into the port is not connected (or the connected device is in charge-only mode with no data transfer) the light stays off. It’s a minor design detail but we appreciate it. When configuring our third-party XBOX 360 controller it offered useful visual feedback during the process.
Other handy features you may find on nicer USB hubs include power switches. Some, like the LOFTEK, have a small power button that offers you the ability to toggle the whole hub on and off. Others, like the Etekcity 10 Port USB 3.0 Hub, have multiple power toggles for different individual ports or sets there of. If you have peripherals that can be powered on and off via USB signal or you just want to easily disable access to certain devices without unplugging them, the extra switches are a very handy little addition.
With a little careful consideration in regard to build quality, how much power you need, the number of ports you require, and a little fine-print reading to make sure you’re getting the extras you want, you’re certain to end up with a dependable USB hub that meets all your needs.

USB 3.0 is the third major version of the Universal Serial Bus (USB) standard for interfacing computers and electronic devices. Among other improvements, USB 3.0 adds the new transfer rate referred to as SuperSpeed USB (SS) that can transfer data at up to 5 Gbit/s (625 MB/s), which is about 10 times faster than the USB 2.0 standard. It is recommended that manufacturers distinguish USB 3.0 connectors from their USB 2.0 counterparts by using blue color for the Standard-A receptacles and plugs,[2] and by the initials SS.[3]
USB 3.1, released in July 2013, is the successor standard that replaces the USB 3.0 standard. USB 3.1 preserves the existing SuperSpeed transfer rate, giving it the new label USB 3.1 Gen 1,[4][5] while defining a new SuperSpeed+ transfer mode, called USB 3.1 Gen 2[4] which can transfer data at up to 10 Gbit/s over the existing USB-type-A and USB-C connectors (1250 MB/s, twice the rate of USB 3.0).[6][7]
USB 3.2, released in September 2017, replaces the USB 3.1 standard. It preserves existing USB 3.1 SuperSpeed and SuperSpeed+ data modes and introduces two new SuperSpeed+ transfer modes over the USB-C connector using two-lane operation, with data rates of 10 and 20 Gbit/s (1250 and 2500 MB/s).

Overview[edit]
The USB 3.0 specification is similar to USB 2.0, but with many improvements and an alternative implementation. Earlier USB concepts such as endpoints and the four transfer types (bulk, control, isochronous and interrupt) are preserved but the protocol and electrical interface are different. The specification defines a physically separate channel to carry USB 3.0 traffic. The changes in this specification make improvements in the following areas:
- Transfer speed – USB 3.0 adds a new transfer type called SuperSpeed or SS, 5 Gbit/s (electrically, it is more similar to PCI Express 2.0 and SATA than USB 2.0)[8]
- Increased bandwidth – USB 3.0 uses two unidirectional data paths instead of only one: one to receive data and the other to transmit
- Power management – U0 to U3 link power management states are defined
- Improved bus use – a new feature is added (using packets NRDY and ERDY) to let a device asynchronously notify the host of its readiness, with no need for polling
- Support for rotating media – the bulk protocol is updated with a new feature called Stream Protocol that allows a large number of logical streams within an Endpoint
USB 3.0 has transmission speeds of up to 5 Gbit/s, about ten times faster than USB 2.0 (480 Mbit/s) even without considering that USB 3.0 is full duplex whereas USB 2.0 is half duplex. This gives USB 3.0 a potential total bidirectional bandwidth twenty times greater than USB 2.0.[9]
Architecture and features[edit]
Front view of a Standard-A USB 3.0 connector, showing its front row of four pins for the USB 1.x/2.0 backward compatibility, and a second row of five pins for the new USB 3.0 connectivity. The plastic insert is in the USB 3.0 standard blue color known as Pantone 300C.
In USB 3.0, dual-bus architecture is used to allow both USB 2.0 (Full Speed, Low Speed, or High Speed) and USB 3.0 (SuperSpeed) operations to take place simultaneously, thus providing backward compatibility. The structural topology is the same, consisting of a tiered star topology with a root hub at level 0 and hubs at lower levels to provide bus connectivity to devices.
Data transfer and synchronization[edit]
The SuperSpeed transaction is initiated by a host request, followed by a response from the device. The device either accepts the request or rejects it; if accepted, the device sends data or accepts data from the host. If the endpoint is halted, the device responds with a STALL handshake. If there is lack of buffer space or data, it responds with a Not Ready (NRDY) signal to tell the host that it is not able to process the request. When the device is ready, sends an Endpoint Ready (ERDY) to the host which then reschedules the transaction.
The use of unicast and the limited amount of multicast packets, combined with asynchronous notifications, enables links that are not actively passing packets to be put into reduced power states, which allows better power management.
Data encoding[edit]
The 'SuperSpeed' bus provides for a transfer mode at a nominal rate of 5.0 Gbit/s, in addition to the three existing transfer modes. Accounting for the encoding overhead, the raw data throughput is 4 Gbit/s, and the specification considers it reasonable to achieve 3.2 Gbit/s (400 MB/s) or more in practice.[10]
All data is sent as a stream of eight-bit (one-byte) segments that are scrambled and converted into 10-bit symbols via 8b/10b encoding; this helps the receiver to decode correctly even in the presence of electromagnetic interference (EMI). Scrambling is implemented using a free-running linear feedback shift register (LFSR). The LFSR is reset whenever a COM symbol is sent or received.[10]
Unlike previous standards, the USB 3.0 standard does not specify a maximum cable length, requiring only that all cables meet an electrical specification: for copper cabling with AWG 26 wires, the maximum practical length is 3 meters (9.8 ft).[11]
Power and charging[edit]
As with earlier versions of USB, USB 3.0 provides power at 5 volts nominal. The available current for low-power (one unit load) SuperSpeed devices is 150 mA, an increase from the 100 mA defined in USB 2.0. For high-power SuperSpeed devices, the limit is six unit loads or 900 mA (4.5 W), almost twice USB 2.0's 500 mA.[10]:section 9.2.5.1 Power Budgeting
The term 'available current' can be misunderstood. It implies that if a low power device or a USB2 device is connected to a USB3 port it can only draw 150 mA or 500 mA from that port. However, the available current for any USB device plugged into a USB3 port is 900 mA (unless it is charging port compliant) as defined by the USB3 spec. The actual current draw is determined by the device capability. The Vbus, pin 1, and Ground, pin 4, are the same for USB 1, 2, or 3. A USB2 HDD with 2 USB2 connectors needing a total of 800 mA will draw full power from a single USB3 port. A USB2 phone will probably charge faster since 900 mA is 'available' to it.
USB 3.0 ports may implement other USB specifications for increased power, including the USB Battery Charging Specification for up to 1.5 A or 7.5 W, or, in the case of USB 3.1, the USB Power Delivery Specification for charging the host device up to 100 W.[12]
Availability[edit]
A USB 3.0 four-port hub, using a VIA Technologies chipset
The USB 3.0 Promoter Group announced on 17 November 2008 that the specification of version 3.0 had been completed and had made the transition to the USB Implementers Forum (USB-IF), the managing body of USB specifications.[13] This move effectively opened the specification to hardware developers for implementation in future products.
The first USB 3.0 consumer products were announced and shipped by Buffalo Technology in November 2009, while the first certified USB 3.0 consumer products were announced on 5 January 2010, at the Las Vegas Consumer Electronics Show (CES), including two motherboards by ASUS and Gigabyte Technology.[14][15]
Manufacturers of USB 3.0 host controllers include, but are not limited to, Renesas Electronics, Fresco Logic, ASMedia, Etron, VIA Technologies, Texas Instruments, NEC and Nvidia. As of November 2010, Renesas and Fresco Logic[16] have passed USB-IF certification. Motherboards for Intel's Sandy Bridge processors have been seen with Asmedia and Etron host controllers as well. On 28 October 2010, Hewlett-Packard released the HP Envy 17 3D featuring a Renesas USB 3.0 host controller several months before some of their competitors. AMD worked with Renesas to add its USB 3.0 implementation into its chipsets for its 2011 platforms.[needs update] At CES2011, Toshiba unveiled a laptop called 'Toshiba Qosmio X500' that included USB 3.0 and Bluetooth 3.0, and Sony released a new series of Sony VAIO laptops that would include USB 3.0. As of April 2011, the Inspiron and Dell XPS series were available with USB 3.0 ports, and, as of May 2012, the Dell Latitude laptop series were as well; yet the USB root hosts failed to work at SuperSpeed under Windows 8. On 11 June 2012, Apple announced new MacBook Airs and MacBook Pro with USB 3.0.
Adding to existing equipment[edit]

In laptop computers that lack USB 3.0 ports but have an ExpressCard slot, USB 3.0 ports can be added by using an ExpressCard-to-USB 3.0 adapter. Although the ExpressCard port itself is powered from a 3.3 V line, the connector also has a USB 2.0 port available to it (some express cards actually use the USB 2.0 interface rather than the true express card port). However, this USB 2.0 port is only capable of supplying the power for one USB 3.0 port. Where multiple ports are provided on the express card, additional power will need to be provided.[citation needed]
Additional power for multiple ports on a laptop PC may be derived in the following ways:
- Some ExpressCard-to-USB 3.0 adapters may connect by a cable to an additional USB 2.0 port on the computer, which supplies additional power.
- The ExpressCard may have a socket for an external power supply.
- If the external device has an appropriate connector, it can be powered by an external power supply.
- USB 3.0 port provided by an ExpressCard-to-USB 3.0 adapter may be connected to a separately-powered USB 3.0 hub, with external devices connected to that USB 3.0 hub.
On the motherboards of desktop PCs which have PCI Express (PCIe) slots (or the older PCI standard), USB 3.0 support can be added as a PCI Express expansion card. In addition to an empty PCIe slot on the motherboard, many 'PCI Express to USB 3.0' expansion cards must be connected to a power supply such as a Molex adapter or external power supply, in order to power many USB 3.0 devices such as mobile phones, or external hard drives that have no power source other than USB; as of 2011, this is often used to supply two to four USB 3.0 ports with the full 0.9 A (4.5 W) of power that each USB 3.0 port is capable of (while also transmitting data), whereas the PCI Express slot itself cannot supply the required amount of power.
If faster connections to storage devices are the reason to consider USB 3.0, an alternative is to use eSATAp, possibly by adding an inexpensive expansion slot bracket that provides an eSATAp port; some external hard disk drives provide both USB (2.0 or 3.0) and eSATAp interfaces.[15] To ensure compatibility between motherboards and peripherals, all USB-certified devices must be approved by the USB Implementers Forum (USB-IF). At least one complete end-to-end test system for USB 3.0 designers is available on the market.[17]
Adoption[edit]
The USB Promoter Group announced the release of USB 3.0 on November 2008. On 5 January 2010, USB-IF announced the first two certified USB 3.0 motherboards, one by Asus and one by Gigabyte.[15][a] Previous announcements included Gigabyte's October 2009 list of seven P55 chipset USB 3.0 motherboards,[20] and an ASUS motherboard that was cancelled before production.[21]
Commercial controllers were expected to enter into volume production in the first quarter of 2010.[22] On 14 September 2009, Freecom announced a USB 3.0 external hard drive.[23] On 4 January 2010, Seagate announced a small portable HDD bundled with an additional USB 3.0 ExpressCard, targeted for laptops (or desktops with ExpressCard slot addition) at the CES in Las Vegas Nevada.[24][25]
The Linux kernel mainline contains support for USB 3.0 since version 2.6.31, which was released in September 2009.[26][27][28]
FreeBSD supports USB 3.0 since version 8.2, which was released in February 2011.[29]
Windows 8 was the first Microsoft operating system to offer built in support for USB 3.0.[30] In Windows 7 support was not included with the initial release of the operating system.[31] However, drivers that enable support for Windows 7 are available through websites of hardware manufacturers.
Intel released its first chipset with integrated USB 3.0 ports in 2012 with the release of the Panther Point chipset. Some industry analysts have claimed that Intel was slow to integrate USB 3.0 into the chipset, thus slowing mainstream adoption.[32] These delays may be due to problems in the CMOS manufacturing process,[33] a focus to advance the Nehalem platform,[34] a wait to mature all the 3.0 connections standards (USB 3.0, PCIe 3.0, SATA 3.0) before developing a new chipset,[35][36] or a tactic by Intel to favor its new Thunderbolt interface.[37] Apple, Inc. announced laptops with USB 3.0 ports on 11 June 2012, nearly four years after USB 3.0 was finalized.
AMD began supporting USB 3.0 with its Fusion Controller Hubs in 2011. Samsung Electronics announced support of USB 3.0 with its ARM-based Exynos 5 Dual platform intended for handheld devices.
Issues[edit]
Speed and compatibility[edit]
Various early USB 3.0 implementations widely used the NEC/Renesas µD72020x family of host controllers,[38] which are known to require a firmware update to function properly with some devices.[39][40][41]
A factor affecting the speed of USB storage devices (more evident with USB 3.0 devices, but also noticeable with USB 2.0 ones) is that the USB Mass Storage Bulk-Only Transfer (BOT) protocol drivers are generally slower than the USB Attached SCSI protocol (UAS[P]) drivers.[42][43][44][45]
On some old (2009–2010) Ibex Peak-based motherboards, the built-in USB 3.0 chipsets are connected by default via a 2.5 GT/sPCI Express lane of the PCH, which then did not provide full PCI Express 2.0 speed (5 GT/s), so it did not provide enough bandwidth even for a single USB 3.0 port. Early versions of such boards (e.g. the Gigabyte Technology P55A-UD4 or P55A-UD6) have a manual switch (in BIOS) that can connect the USB 3.0 chip to the processor (instead of the PCH), which did provide full-speed PCI Express 2.0 connectivity even then, but this meant using fewer PCI Express 2.0 lanes for the graphics card. However, newer boards (e.g. Gigabyte P55A-UD7 or the Asus P7P55D-E Premium) used a channel bonding technique (in the case of those boards provided by a PLX PEX8608 or PEX8613 PCI Express switch) that combines two PCI Express 2.5 GT/s lanes into a single PCI Express 5 GT/s lane (among other features), thus obtaining the necessary bandwidth from the PCH.[46][47][48]
Radio frequency interference[edit]
USB 3.0 devices and cables may interfere with wireless devices operating in the 2.4 GHz ISM band. This may result in a drop in throughput or complete loss of response with Bluetooth and Wi-Fi devices.[49] Various strategies can be applied to resolve the problem, ranging from simple solutions such as increasing the distance of USB 3.0 devices from Wi-Fi routers and Bluetooth devices, to applying additional shielding around internal computer components.[50]
There were some devices (for example Vivo Xplay 3S) which were promised to come with USB 3.0, however, ultimately didn't ship with USB 3.0, because of manufacturers' inability to resolve the electromagnetic interference caused by USB 3.0.[51]
Connectors[edit]
USB 3.0 Standard-A receptacle (top, in the blue color 'Pantone 300C'), Standard-B plug (middle), and Micro-B plug (bottom)
A USB 3.0 Standard-A receptacle accepts either a USB 3.0 Standard-A plug or a USB 2.0 Standard-A plug. Conversely, it is possible to plug a USB 3.0 Standard-A plug into a USB 2.0 Standard-A receptacle. This is a principle of backward compatibility. The Standard-A is used for connecting to a computer port, at the host side.
A USB 3.0 Standard-B receptacle accepts either a USB 3.0 Standard-B plug or a USB 2.0 Standard-B plug. Backward compatibility applies to connecting a USB 2.0 Standard-B plug into a USB 3.0 Standard-B receptacle. However, it is not possible to plug a USB 3.0 Standard-B plug into a USB 2.0 Standard-B receptacle, due to a physically larger connector. The Standard-B is used at the device side.
Since USB 2.0 and USB 3.0 ports may coexist on the same machine and they look similar, the USB 3.0 specification recommends that the Standard-A USB 3.0 receptacle have a blue insert (Pantone 300C color). The same color-coding applies to the USB 3.0 Standard-A plug.[10]:sections 3.1.1.1 and 5.3.1.3
USB 3.0 also introduced a new Micro-B cable plug, which consists of a standard USB 1.x/2.0 Micro-B cable plug, with an additional 5-pin plug 'stacked' inside it. That way, the USB 3.0 Micro-B host connector preserved its backward compatibility with the USB 1.x/2.0 Micro-B cable plugs. However, it is not possible to plug a USB 3.0 Micro-B plug into a USB 2.0 Micro-B receptacle, due to a physically larger connector.To be perfectly clear, you can run a device with a USB3 Micro-B socket on a USB2 Micro-B cable at USB2 speeds.
Pinouts[edit]
USB 3.0 Standard-A plug (top) and receptacle (bottom), with annotated pins
The connector has the same physical configuration as its predecessor but with five more pins.
The VBUS, D−, D+, and GND pins are required for USB 2.0 communication. The additional USB 3.0 pins are two differential pairs and one ground (GND_DRAIN). The two additional differential pairs are for SuperSpeed data transfer; they are used for full duplex SuperSpeed signaling. The GND_DRAIN pin is for drain wire termination and to control EMI and maintain signal integrity.

---|---|---|---|---|
A connector | B connector | |||
Shell | N/A | Shield | Metal housing | |
1 | Red | VBUS | Power | |
2 | White | D− | USB 2.0 differential pair | |

Backward compatibility[edit]
USB Micro-B USB 2.0 vs USB Micro-B SuperSpeed (USB 3.0)
USB 3.0 and USB 2.0 (or earlier) Type-A plugs and receptacles are designed to interoperate.
USB 3.0 Type-B receptacles, such as those found on peripheral devices, are larger than in USB 2.0 (or earlier versions), and accept both the larger USB 3.0 Type-B plug and the smaller USB 2.0 (or earlier) Type-B plug. USB 3.0 Type B plugs are larger than USB 2.0 (or earlier) Type-B plugs; therefore, USB 3.0 Type-B plugs cannot be inserted into USB 2.0 (or earlier) Type-B receptacles.
Micro USB 3.0 (Micro-B) plug and receptacle are intended primarily for small portable devices such as smartphones, digital cameras and GPS devices. The Micro USB 3.0 receptacle is backward compatible with the Micro USB 2.0 plug.
A receptacle for eSATAp, which is an eSATA/USB combo, is designed to accept USB Type-A plugs from USB 2.0 (or earlier), so it also accepts USB 3.0 Type-A plugs.
USB 3.1[edit]
In January 2013 the USB group announced plans to update USB 3.0 to 10 Gbit/s (1.25 GB/s).[54] The group ended up creating a new USB specification, USB 3.1, which was released on 31 July 2013,[55] replacing the USB 3.0 standard. The USB 3.1 specification takes over the existing USB 3.0's SuperSpeed USB transfer rate, also referred to as USB 3.1 Gen 1, and introduces a faster transfer rate called SuperSpeed USB 10 Gbps, referred to as USB 3.1 Gen 2,[56] putting it on par with a single first-generation Thunderbolt channel. The new mode's logo features a caption stylized as SUPERSPEED+[57]. The USB 3.1 Gen 2 standard increases the maximum data signaling rate to 10 Gbit/s (1.25 GB/s), double that of SuperSpeed USB, and reduces line encoding overhead to just 3% by changing the encoding scheme to 128b/132b.[58] The first USB 3.1 Gen 2 implementation demonstrated real-world transfer speeds of 7.2 Gbit/s.[59]
The USB 3.1 standard is backward compatible with USB 3.0 and USB 2.0. It defines the following transfer modes:
- USB 3.1 Gen 1 - SuperSpeed, 5 Gbit/s (0.625 GB/s) data signaling rate over 1 lane using 8b/10b encoding; the same as USB 3.0.
- USB 3.1 Gen 2 - SuperSpeed+, new 10 Gbit/s (1.25 GB/s) data rate over 1 lane using 128b/132b encoding.
This rebranding of USB 3.0 as 'USB 3.1 Gen 1' allows manufacturers to advertise products with transfer rates of only 5 Gbit/s as 'USB 3.1,' omitting the generation.[60]
USB 3.2[edit]
On 25 July 2017, a press release from the USB 3.0 Promoter Group detailed a pending update to the USB Type-C specification, defining the doubling of bandwidth for existing USB-C cables. Under the USB 3.2 specification, existing SuperSpeed certified USB-C 3.1 Gen 1 cables will be able to operate at 10 Gbit/s (up from 5 Gbit/s), and SuperSpeed+ certified USB-C 3.1 Gen 2 cables will be able to operate at 20 Gbit/s (up from 10 Gbit/s). The increase in bandwidth is a result of multi-lane operation over existing wires that were intended for flip-flop capabilities of the USB-C connector.[61][62]
The USB 3.2 standard is backward compatible with USB 3.1/3.0 and USB 2.0. It defines the following transfer modes:
- USB 3.2 Gen 1×1 - SuperSpeed, 5 Gbit/s (0.625 GB/s) data signaling rate over 1 lane using 8b/10b encoding, the same as USB 3.1 Gen 1 and USB 3.0.
- USB 3.2 Gen 1×2 - SuperSpeed+, new 10 Gbit/s (1.25 GB/s) data rate over 2 lanes using 8b/10b encoding.
- USB 3.2 Gen 2×1 - SuperSpeed+[57], 10 Gbit/s (1.25 GB/s) data rate over 1 lane using 128b/132b encoding, the same as USB 3.1 Gen 2.
- USB 3.2 Gen 2×2 - SuperSpeed+[citation needed], new 20 Gbit/s (2.5 GB/s) data rate over 2 lanes using 128b/132b encoding.
In May 2018, Synopsys demonstrated the first USB 3.2 Gen 2x2 connection, where a Windows PC was connected to a storage device, reaching a speed of 1.6 GB/s average.[63][64]
USB 3.2 is supported with the default Windows 10 USB drivers and in Linux Kernel 4.18.[63][64][65]

I have a relatively up to date computer I had built for my observatory a few months ago with Windows 7 Pro installed. I use the computer for astronomical imaging with webcams and CCD long exposure cameras attached to my telescope. My newer webcams are USB 3.0 and I had operated them from a HooToo 7-port USB 3.0 hub (HT-UH010) along with some USB 2.0 devices. All was working just fine under Windows 7. Then came the Windows 10 upgrade. Now the device manager shows that I have the video camera installed and it is working properly when I am using the camera through the hub, but on attempting video capture I get an immediate 'capture failed' message. On the other hand, when I hook up through one of the USB 3.0 ports on the mother board, the camera works just fine. The HooToo hub did not come with any software and was intended to run with the generic hub drivers. On the HooToo website is the disclaimer: 'Windows 2000, XP, Vista, 7, 8 (does NOT support Windows 8.1)', no mention of Windows 10. I wish I had not done the Win10 upgrade. Can I go back? What about the newer computer that arrived with Win10 installed? Is this a bug that I can expect to be fixed in an update soon?

What about the newer computer that arrived with Win10 installed? Is this a bug that I can expect to be fixed in an update soon?
