Common Solutions to Fixing USB Device Not Recognized Errors
First things first – always make sure your USB device drivers
are up-to-date. Missing, corrupt or outdated device drivers are responsible for a lot of PC errors.
After ensuring your drivers are updated, try the following solutions (in order):
1. Unplug your computer. Don’t just turn it off with the power button, you need to actually unplug the cable from the power supply for at least 1 minute. This often resets your USB hub on your motherboard.
2. Remove the battery. If you computer is a laptop
, remove the battery for at least 2-3 minutes before plugging it back in and restarting Windows
3. Uninstalling root hub drivers. If steps 1 and 2 above do not work, try the following:
Unplug all USB devices from your computer.
Go to Device Manager in Windows 7
Uninstall EACH Root Hub USB Driver
Power off your computer and UNPLUG THE CABLE FROM THE POWER SUPPLY, just don’t shut it down.
Reconnect the power supply cable and turn your computer on after 2-3 minutes.
Reconnect each external USB device. (i.e. mouse, keyboard, thumb drive, etc.)
4. If you still have issues and cannot get rid of “USB device not recognized” error messages you can try disabling USB 2.0 devices which should remove the error message and “fix” the problem (although it’s more of a band aid then an actual solution) but your USB devices will now run at the slower USB 1.1 speed.
