Microsoft does, however, ship a tool called USBView along with the Windows SDK that’s quite helpful in determining the detailed features of a USB Device. As such, it’s difficult to determine the specific USB version and its transfer speed from Device Manager, or any other tool that comes packaged with Windows out of the box. Windows detects most USB devices as Generic by default in Device Manager. Click on a device under one of the USB controllers to know more about its specifications in the bottom part of the window.Īmong the specifications, you should find the Speed attribute, which would indicate the USB version your device is currently operating on (Up to 480 Mbps for USB 2.0, up to 5 Gbps for USB 3.0 and so on).The USB Device Tree on the top will show all the different USB Controllers available on the Mac.In the System Report screen, scroll and click on USB under Hardware section on the left pane.Go to About This Mac and click on System Report in the Overview tab.Click on the Apple logo in the top-left corner of the screen.Here’s how to find out the USB version supported by your USB controller and/or the device. You may also identify the USB version supported by the USB host controller on your computer or the device, by looking at the System Information provided by your computer’s operating system. Identify the USB version from System Report or Device Manager Thus, we need a different way to distinctively identify the different generations of USB devices, and one sure-shot way of doing so is to plug the device into a computer and let the operating system reveal it for you. The only color codings that seem to hold true consistently are those for the Blue and Red/Yellow indicators. In modern times, though, this color coding seems to be no longer distinctively followed.įor instance, nowadays, you could easily come across USB devices that are black or white in color, but in fact be fully compatible with USB 3.x. White or Black USB Connector - Older Generation USBĭuring earlier generations of USB devices, a white USB connector would signify a USB 1.x compatible device, while a black connector would signify a USB 2.0 device. These connectors are usually found in laptops and desktop computers and are useful for charging external USB devices, such as smartphones. Red or yellow USB connectors always supply power, regardless of whether the host is inactive, standby or sleep mode. These connectors do not indicate any particular USB specification, but rather point towards a specific feature. ![]() Some USB devices may come with a red or yellow plastic body on the connector face. Red or Yellow USB Connector - Sleep & Charge These are one of the fastest USB devices available today, offering data transfer speeds between 5 – 20 Gbps. The color indicates that the device is USB 3.x compatible. Most USB devices that we see these days would have a blue colored plastic body on the connector face. The most common color indicators for USB devices are as follows. USB Type-A host controllers and devices usually follow a certain color coding on their connectors to indicate the USB version they support. In this article, we’ll help you to identify the version of USB supported by your host controller (on your computer) as well as that of the USB accessory (flash drive, data transfer cable, etc.) you’re trying to connect. ![]() So, the hardware limitations of one component (host or device) also limit the data transfer speed of the other. USB Type-A is usually cross-compatible if a USB 2.0 device is plugged into a USB 3.x port (or vice versa), the connection will automatically be downgraded to USB 2.0. And to ensure that you get high-speed data transfers from your USB storage, not only do you need a USB 3.x compatible device, the USB host controller installed on your computer must be 3.x as well. If you have a USB Type-C device, it fully supports the USB 3.1 & 3.2 specifications, which provides one of the fastest modes of data transfer, enabling a host of functionalities, including Gigabit Ethernet, 4K screen mirroring and more.īut external storage devices, like flash drives or external hard disks, often come with a regular Type-A connection. ![]() ![]() USB 3.0: Data Rate - Up to 625 MB/s (SuperSpeed) USB 1.0: Data Rate - Up to 187.5 kB/s (Low Speed) 1.5 MB/s (Full Speed)
