I think I have the pinout! My buddy has a Z600 with the same connector and he was nice enough to take a multimeter to the USB ports and the connector:
That's good news. So from that it appears that HP's colour coding is:
Red = VBus (+5V)
Black = Ground
Green = D+
White = D-
Your diagram needs to be flipped to visualise it directly on to the motherboard header because pins 1 and 2 on the left of the yellow header are 5V (Red B/Red C on your diagram).
