What should you do when you plug a USB device into your PC and it doesn’t work? You could try removing it and then plugging it in again, but if Windows is at fault this won’t help. The problem is usually caused by a fault in the Windows USB subsystem, and the quickest way to fix it is to reinstall the driver for the USB controller. This will reset the USB subsystem, meaning you can get your device working again in a few minutes.

To apply this fix:
 * 1) Unplug all the USB devices from your PC.
 * 2) Press [**Windows Key**] + [**R**], type **devmgmt.msc** and press [**Enter**].
 * 3) In the Device Manager Window scroll to the **Universal Serial Bus controllers** option and click on the **+** symbol.
 * 4) Right-click on each entry listed under the controllers heading and then click **Uninstall**.
 * 5) Repeat step 4 until all of the devices under the controllers heading are removed.
 * 6) Restart your PC and the drivers for your USB controllers will be automatically re-installed.
 * 7) Once your PC has rebooted, reconnect your USB devices and they should all now work.
