1) You can use Device Manager to check the status of a plugged in but not recognised USB drive by checking if the “Universal Serial Bus Controller” shows up as working correctly or has a yellow exclamation mark on it when the device is connected.

2) In device manager down the bottom you will see “Universal Serial Bus Controllers” click on the plus sign beside it which will expand that tree. You will see “USB ROOT HUB”, right-click on those 1 by 1 (keep all your usb devices plugged in) and click on “uninstall”. When you have uninstalled them all shut down your computer completely (DO NOT UNPLUG ANY USB DEVICE) then reboot your computer……….windows should do the rest and reinstall them for you properly.
