this might be useful Usb connectors to motherboard
Just follow the labels on the pins 1 +5V = power or pwr = VREG_FP_USBPWR0 = VCC 1 2 +5V = power or pwr = VREG_FP_USBPWR1 = VCC 2 3 USB_FP_P0- = DATA –1 4 USB_FP_P1- = DATA –2 5 USB_FP_P0+ = DATA +1 6 USB_FP_P1+ = DATA +2 7 GROUND = GND 1 8 GROUND = GND 2
ground is obvious usb2- = data2- usb2+ = data2+ The case pins will be marked 1 and 2, but the motherboard 3 and 4 (because 1 and 2 for the motherboard are on the back connectors of the board.) So your set of four pins for port1 on the case gose to the 4 pins marked 3 on the board. And the set of four marked for port2 on the case go to the set marked 4 on the board. So you take a 4 wire set for each port +5v, data+, data-, and Ground and match them up to the pins on the board. The colours of the cables are not relevant - it's what's marked on the connectors that counts.
