Do your Device Manager entries match what Nick showed in his post ?
If you don't have "Root Hubs", you won't be getting any power.
The Root Hub provides the power (at least, deleting USB entries
in Device Manager, and getting my Root Hubs back, put power back
on one of my dead ports). Don't give up on the hardware , until at
least trying a clean install of SP1 - then see if the USB ports are
still dead. If you have a spare disk, try a test install with that.
