well i felt like it was time for a reformat and new install of xp. i install xp and update all my drivers and what not. now i remember when i first installed xp and got my comp up and running my usb ports would not work until i installed windows xp sp2. so i install that, but my comp won't recognize any usb devices. in my device mananger two usb controllers are recognized and one is not, but whenever i try to plug in a device, like a printer, it's never detected, what gives?
