The first steps to take to fixing the USB port issue is to open Device Manager (in Control Panel), and remove everything under Universal Serial Bus controllers. To remove them, right click on each of the entries under this category and choose uninstall from the list. Click this button - it will warn you that you are about to remove the device from your system. Click ok, as this is what you want to do. Repeat this with every entry under Universal Serial Bus controllers until they are all gone. Reboot your system, and windows will detect the new hardware and re-install the drivers. Under normal circumstances, this should be enough to get your USB ports working again.
