Help /pls

Hey guise! If you are a "techie" and you are reading this, I would love some help! c:
My USB 2.0 Drivers are crashed or something (the glitch with Win XP SP2) and won't recognize USB 2.0 , but recognizes it as USB 1.1 . If you have suggestions, they will be appreciated.

Yeah, I've used all ports, and reistalled all... Microsoft conformed it was their fault, and their suggestion was to reinstall, but that didnt work for me :c
