Question : Problem: none of the USB ports responding

I put a fresh XP image on a T1145 eMachine.
Everything is working fine except for the front and rear USB ports.  I've check the connections.
Device Manager sez that they are working fine.  I uninstalled them any way.  Then scanned for new hardware and still nothing.  I booted to an Knoppix disk and from there they didn't work either.
When I plug in a thumb drive the light on it does light up, so there is power.
there weren't any drivers to download from the manufactures website.

Any help would be great.
Thanks
