Universal Serial Bus (USB) provides an expandable, hot-pluggable Plug and Play serial interface that ensures a standard, low-cost connection for peripheral devices such as keyboards, mice, joysticks, printers, scanners, storage devices, modems, and video conferencing cameras. Migration to USB is recommended for all peripheral devices that use legacy ports such as PS/2, serial, and parallel ports.

The USB-IF is a Special Interest Groups (SIGs) that maintains the Official USB Specification, test specifications and tools.

Windows operating systems include native support for USB host controllers, hubs, and devices and systems that comply with the official USB specification. Windows also provides programming interfaces that you can use to develop device drivers and applications that communicate with a USB device.

See full list on docs.microsoft.com. Feb 18, 2015 The small microprocessor on the motherboard will reload the drivers and your USB ports should hopefully be recognizing devices again. So first turn off your computer using the Shut Down option in Windows or pressing the power button and then UNPLUG the PC from the wall outlet. Let it sit for several minutes and then plug it back in. Some USB devices, such as printers, scanners, and copiers require that the USB device software and drivers be installed before connecting the USB device to the computer. Always follow the installation documentation from the USB device manufacturer. While troubleshooting the USB device, you might need to disconnect the USB device from the computer. Information about a USB device is stored in segments of its ROM (read-only memory). These segments are called descriptors. An interface descriptor can identify a device as belonging to one of a finite number of classes. The HID class is the primary focus of this document. A USB/HID class device uses a corresponding HID class driver to retrieve.

The USB device malfunctioned and not recognized error has frustrated a large number of users. If you are one of the victims, here are some fixes you can try to resolve the issue and make your device detected.

How to Fix USB Device Not Recognized in Windows 10/8/7/XP/Vista

If your device is not recognized at the moment, you can try the below six solutions to make it show up again. You don't have to try every method, but we strongly recommend you follow the sequence, which our experts have tried many times.

Fix 1. Unplug your computer to fix the USB device malfunctioned

It sounds like a piece of cake thing to do, but it works! For most of not recognizing USB gadgets, there is typically nothing wrong. A computer restart could solve it. This way is meant to reboot the motherboard, which has all of the computer hardware connected to, including the USB ports. Rebooting the motherboard usually helps solve the temporary insufficient power supply for outside devices.

Step 1. Cut your computer power at its source, which is unplugging your computer from the wall outlet.

Step 2. Leave the computer alone for a few minutes, and then replug it in the wall outlet for a restart.

Step 3. Now check if the computer is able to detect the USB device and assign a drive letter to it.

If this fix failed, don't panic, the next methods are also doable.

Fix 2. Change the USB cable or USB port to Fix USB device not recognized

Is the computer's USB port working properly? You need to check the available USB ports one by one to see whether it is a computer hardware problem or a problem with the device itself. If changing to another port solves the problem, then there is something wrong with the previous port. You can give up that broken port, or send your computer for repair.

Fix 3. Update/Rollback a device driver if the USB device not recognized

Device Manager operation is another widely suggested way to troubleshoot a non-recognizable USB device on Youtube and IT forums. Does this method apply to your situation? Go on to have a check.

Step 1. Type device manager in the search box to open Device Manager.

Or you can press Windows + R keys simultaneously to bring up the Run box, then type devmgmt.msc, and hit Enter.

Step 2. Expand 'Universal Serial Bus Controllers' and you will see the item called 'Generic USB Hub'. Righ-click on the first Generic USB Hub and choose Properties.

Step 3. Now, navigate to the 'Driver' tab, choose 'Update Driver...'.

Step 4. When asked how do you want to search for driver software, there are two options.

1. Search automatically for updated driver software

This way is an automatic update by Windows. When it finished, all you need to do is to disconnect the USB device, restart the computer and reconnect it again. Windows will install the latest driver for you.

2. Browse my computer for driver software

When you choose this option, you need to continue with the other pop up 'let me pick from a list of device drivers on my computer.'

From the list, select Generic USB hub, which normally the only choice. Click 'Next' and then Windows will install the driver for you.

Tip
If updating the driver doesn't help solve the USB device problem, don't suspend though, try to update each Generic USB Hub until updated them all for once.

In the same path to update the driver, you can also try to roll back to the previous driver before the error occurs. Instead of selecting 'Update Driver' in the 'Driver' tab, choose 'Roll Back Driver' this time.

The changes made on the computer power and the device driver should take effect, and your USB device will no longer report issues. Otherwise, try the rest three methods one by one.

Fix 4. Fix USB Root Hub to Fix USB drive not recognized

The USB root hub is the software driver that lets you connect multiple USB peripherals to your computer. Most computers have multiple root hubs so you can share the data bus across multiple devices. So if the computer cannot recognize your USB drive, you can try to fix the USB root hub.

Step 1. Open Device Manager. Find the Universal Serial Bus controllers option and single click it to expand.

Step 2. Find the USB Root Hub option in this category. Right-click it and choose Properties.

Step 3. Go to the Power Management tab and uncheck the 'Allow the computer to turn off this device to save power' option. Then click OK to save your change.
