Ulrick > Dumb question - can you plug in something like a USB light and see if it powers up? It does sound like a hardware problem. If it does not, check if you plugged in the connector on the motherboard 1 row down from where it should be. With some motherboards it is almost impossible to see the pins because the plug blocks your line of site. If possible, try plugging the cable into another connector as well. With 12 USB ports, I am guessing you have more then one header. Mikkel -- I am not a number, I am an individual with a unique number.
