Hi, I'm no longer able to use my usb 2.0 mouse in Windows 8.1. and I want that back. Can I use an earlier driver for my usb 3.0 ports so that I'm able to keep using usb 2.0 devices? With Microsoft support I get absolutely nowhere. Thanks for any advice. By the way I 've already tried most solutions like uninstalling the usb drivers, it doesn't help.
