I'm having a lot of trouble with my USB ports and I was hoping someone could help me fix the problem.
My motherboard has four USB ports in the back of it. There are also two USB ports in the front of my PC which are connected to the motherboard. I also have a card inserted into the motherboard which adds an extra four USB ports, making ten in total.
One of the USB ports on the card works fine, but the other nine USB ports don't. When I plug a device into them, my PC either does nothing, says that the device has malfunctioned or says that the device cannot be recognised.
All the USB devices I've tried work only in that one port.
Please can someone suggest how to correct this and get the others working?
Here are the details of my PC:

Processor - Intel Q8300 Core 2 Quad (2.50GHz/4M/1333/05A/Socket: 775)
Motherboard - ASUS P5N-E SLI
