“USB device not recognized” is an error that usually occurs on Windows computers when you plug in a USB device. When Windows generates such an error, the USB will not show up on your computer, and you can’t access your data. In different situations, the error is followed by various messages:
“The last USB device you connected to this computer malfunctioned, and Windows does not recognize it.”
“One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.”
How to Fix USB Device Not Recognized in Windows
If your device is not recognized on your computer, try the six solutions below to make it show up again. We strongly recommend you follow the below methods in sequence. Since there are many reasons that lead to a Windows failed to recognize the USB device error, each method is for a specific scenario.
Fix 1. Unplug Your Computer from the Power Source
This sounds like a piece of cake thing to do but it works! For most unrecognized USB devices, there is typically nothing wrong. A simple computer restart could resolve the issue. This method reboots 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 unplugged for a few minutes, and then plug it back into the wall outlet.
Step 3. Check if the computer detects the USB device and assigns it a drive letter.
If this fix didn’t work, don’t panic. Follow the other fixes below.
Fix 2. Change the USB Port
Is your computer’s USB port not working properly? Check the available USB ports one by one and 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 on that broken port, or send your computer for repair.
Fix 3. Uninstall USB Device Driver to Make USB Recognizable
If the USB drivers are unstable or damaged, this method removes those drivers. Know that uninstalling the drivers can cause all USB ports to become dysfunctional.
Step 1. Right-click on the Windows logo and choose Device Manager.
Step 2. Find and expand Universal Serial Bus controllers, right-click on any of the USB drivers, and click Uninstall. Do this for all USB drivers one by one.
Step 3. Restart your PC. The USB drivers will automatically reinstall and solve the corrupted USB devices problem.
Fix 4. Update/Rollback a Device Driver
Many YouTube videos and IT forums suggest using Device Manager to troubleshoot non-recognizable USB devices. Give this method a go and see if it works for you.
Step 1. Right-click on the Windows logo and choose Device Manager.
Step 2. Expand “Universal Serial Bus Controllers” and you will see an item called “Generic USB Hub”. Righ-click on the first Generic USB Hub and choose “Properties”.
Step 3. Navigate to the “Driver” tab and 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 uses an automatic update by Windows. When this is finished, all you need to do is to disconnect the USB device, restart the computer, and reconnect the USB device 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 pop-up “let me pick from a list of device drivers on my computer.”
From the list, select Generic USB hub, which is normally the only choice. Click “Next” and then Windows will install the driver for you.
- If updating the driver doesn’t help solve the USB device problem, try to update each Generic USB Hub until you have updated all.
In the same path as update the driver, roll back to the previous driver when the error didn’t occur. 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. If this is not the case, try the other three methods one by one.
Fix 5. Change the USB Selective Suspend Settings
Another possible reason your USB malfunctions is that the hub driver suspends the USB automatically. In this case, changing the USB selective suspend settings could help.
Step 1. Right-click on the Windows icon and click Power Options.
Step 2. In the Choose or customize a power plan window, click Change plan setting.
Step 3. In the Edit Plan Settings window, click Change advanced power settings.
Step 4. In the Power Options window, find and expand USB settings, expand USB selective suspend settings, and Disable both On battery and Plugged in settings.
Step 5. Click Apply and then OK to save the settings.
Fix 6. Fix USB Root Hub

Step 1. Open Device Manager, find the Universal Serial Bus controllers option and single-click it to expand it.
Step 2. Find the USB Root Hub option in this category, right-click it, and choose Properties.
