USB device not recognized when you plug something in
Windows doesn't recognize your USB device because the driver is missing or corrupted. Unplug your computer, restart your computer, then plug it back in. Windows will reinstall the driver and it will work. This fixes it for almost everyone.
When Windows says a USB device is not recognized, it means the driver — the software that tells Windows how to use that device — is missing or broken. Restarting your computer clears out the broken driver, and Windows automatically installs the right one when you plug your device back in. If that doesn't work, uninstalling your computer from Device Manager does the same job.
- ✓Check that your USB device works on another computer to confirm your computer itself isn't broken
- ✓Try different USB ports on your computer — sometimes one port is damaged and another will work
- ✓Check if you see your computer in Device Manager, even if it shows as unknown or with a warning mark
Fix-IT-Bot will walk you through each step, just tap, no typing needed.
Skip, I just want a technicianCommon mistakes to avoid
- Trying the same USB port multiple times instead of trying a different one — if one port is broken, another will work
- Not waiting for Windows to finish reinstalling the driver before using your computer — wait 30 seconds after plugging it in
- Assuming your computer is broken when the problem is actually with your computer's USB port
