USB+5V = VCC
USB P7- = +D
USB P7+ = -D
GND = Ground
just make sure you connect the cables of each group to the same USB port-pins on the motherboard, and you'll be fine
(the ...../NC pin is there, so you cant push up the standard usb connector to the motherboard the wrong way around. but that doesnt work out wit lose pin's (I had the same with my case

the NC stands for Not Connected )
I'll have look nto the Audio connector.. dont know that one atm
