post your exact motherboard model number, it might help us more,
on an offchance though, do you also have old style ps2 connectors for mouse/keyboard?
possibly clearing your bios by removing the battery for half an hour may work also,

Did you clear the CMOS/Remove the battery as Motopsychojdn suggested?

Clearing the CMOS usually does the trick and restores your USB port to default.
Now, some boards by default turn off USB support when you clear the CMOS, it's a stupid way to do things, but my old DFI 3200CFX board did this(other than it was an awesome board). I keep an old cheap PS2 keyboard around for times like this, so I could get back into the BIOS and turn the friggin USB keyboard and mouse support back on after a BIOS reset.
