Hoping someone can help. All of the USB ports on my PC have stopped working. When I checked device manager I found yellow question marks next to all USB root hubs and the host controller. I therefore downloaded the necessary drivers from the motherboard manufacturers website and the yellow question marks disappeared. Problem cured I thought. However, the ports still wont recognise and devices I place into them. I re-installed windows xp home but the problem re-occurred. Not sure what to do next.

USB Permissions
Start - Run and type
regedit
Press OK.
Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB.
Right click on the folder and pick permissions. Set to ALLOW.
Do the same for:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR

Thanks Fruit Bat. I'll try that as soon as I get home from work.
