If your device isn't showing up on your computer, try each of the six methods below to get it to reappear. We recommend that you attempt them in the order presented, as each method applies to a specific situation that can cause the “Windows doesn't recognize USB device” error for various reasons.
Note: For other USB issues, including the USB not showing in Disk Management, damaged USB, and USB Code 43, you can refer to the online guide on how to fix USB drives and recover data.
This video consolidates 4 surefire solutions to fix the USB device not recognized issue. For a detailed text guide, refer to the methods below.
This is a very simple fix, but it works! Most unrecognized USB devices just need a quick restart. This will reboot your motherboard, which connects all of your computer's hardware, including the USB ports. A quick reboot can often fix temporary power issues with external devices.
The first step is to unplug the computer – that is, to remove it from its power source.
Step 2: Unplug your computer for a few minutes, then plug it back into the wall.
Step 3: Check if your computer detects the USB device and assigns it a drive letter.
If that doesn't work, don't worry. Try one of the other solutions below.
Did your computer's USB port stop working? Try each available USB port to determine if the problem is with your computer's hardware or the device itself. If it works in a different port, the original one is faulty. You can either stop using the broken port or get your computer repaired.
If the USB driver is corrupted or outdated, this will remove it. Note that uninstalling the driver may cause all USB ports to stop working properly.
Step 1: Right-click the Windows icon and select Device Manager.
Step 2: Look for and expand the “Universal Serial Bus controllers” section. Right-click on any USB driver and select “Uninstall.” Do this for all USB drivers one by one.
Step 3. Restart your computer. The USB driver should automatically reinstall and fix the corrupted USB device.
Many YouTube videos and IT forums suggest using Device Manager to fix unrecognized USB devices. Try this method and see if it works for you.
Step 1: Right-click the Windows icon and select Device Manager.
Step 2: Expand the Universal Serial Bus controllers section, and look for an entry called Generic USB Hub. Right-click the first Generic USB Hub entry, and select Properties.
Step 3: Navigate to the “Driver” tab and select “Update Driver.”
Step 4: When the system asks how to search for driver software, you have two options.
1. Search for driver update software
This will usually be through Windows Update. Once that's done, unplug the USB device, restart your computer, and plug the USB device back in. Windows should install the most up-to-date drivers for you.
2. Search for driver software on my computer
When you select this option, you will be prompted to “Browse my computer for driver software.”
Select “Generic USB Hub” from the list, which should be your only option. Click “Next,” and Windows will automatically install the driver for the hub.
Select the driver you wish to update.
Just like with updating the driver, you can roll back to a previous driver before the error occurred. On the Driver tab, click Roll Back Driver this time instead of Update Driver.
Your power settings and device drivers should now be updated, and your USB devices should be working properly. If the problem persists, try the other three methods.
Another reason your USB device might be having issues is that the hub driver is suspending USB automatically. In this case, changing the USB selective suspend settings might help.
Step 1: Right-click the Windows icon and select “Power Options.”
Step 2: In the Choose or customize a power plan window, click Change plan settings.
Step 3: Click on “Change advanced power settings” in the “Edit Plan Settings” window.
Step 4. In the Power Options window, find and expand USB Settings, then expand USB Selective Suspend Setting, and disable both Battery and On Battery options.
Step 5: Click “Apply,” then “OK” to save your settings.
A USB root hub is a software driver that allows you to connect multiple USB peripheral devices to your computer. Most computers have several root hubs so that the data bus can be shared between many devices. As such, if your computer isn't recognizing your USB drive, try repairing the USB root hub.
Step 1: Open Device Manager and locate the "Universal Serial Bus controllers" option. Click to expand it.
Step 2. Look for the 'Universal Serial Bus controllers' category, right-click on it and select 'Properties'.
Step 3: Go to the Power Management tab, and uncheck the box for “Allow the computer to turn off this device to save power.” Click OK to save your changes.
