Alright, so I'm at that point in the building where you need to hook up all the various wires from the case to the mobo. I've done the important ones except for the USB ports. Coming off the 2 front USB's, I have a VCC, D+, D- and a ground. However, on my motherboard, I have the following "openings": USB +5V w/ - & + USB +6V w/ - & + USB +7V w/ - & + USB +8V w/ - & + What voltages should I be hooking up the two USB ports to?
