so originally all my usb ports except one (the one with my keyboard and mouse by the way i have the keyboard plugged into the computer and the mouse plugged into the keyboard) didn't work. i looked it up and i got some advice to uninstall the usb hubs so i did and then none of the usb ports worked at all (even my mouse and keyboard).i turned off the computer with the power button and turned it back on and it said "found new hardware click wizard to install" the problem: neither the mouse or keyboard work so i cant install it. the weird thing is i can go into the bios by pressing f12 and the keyboard works and the mouse lights up but when i go to windows neither work. i know it is not a problem with the keyboard because it will work in the bios. so what i want to know: how do i fix this? what caused it? and how to get all of my usb ports to work? (not just the keyboard and mouse one). i have Windows XP Media Center Edition.
