lost usb ports, what to do

was messing round with changing my polling rate for a mx500 in windows 7, unfortunately you have to get windows to enable driver signing of non authorised drivers. so after using Driver Signature Enforcement Overrider and trying to run the driver by following these instructions, How to Increase USB Sample Rate in Windows Vista/7 - Page 6
