USB controller issue

[Invisible]

Ok so none of the usb ports work so i can't access bios via keyboard
i can't find anything wrong with the little usb box on the side of the motherboard
keyboard works fine on other comp

When did you first get this problem, and do you mean ALL usb ports on your pc dont work? both front and back ports?
DId anything significant happen before this happened? e.g. moved the pc, added new hardware, etc.

does it work when you boot into windows? if its just the bios then you ahve to get a ps/2 keyboard and enable USB legacy support in the bios. it should be under standard CMOS settings.
