How do you wire usb ports, I have a cable which I ripped off one of those expandable usb pci bracket things, so now I have 2 cable, for each port connected to a blue thing which I plug into my mobo, but how do you wire the usb ports, the ones I have 4 pins coming out and a 5th wider one extending out the side, I then have a red, white, green, black, wires, and another wire un sleeved wire?
