USBs on the front of the case

[Crais]

I connect the cable to the MBO, and they don't work. I disconnect that, put the USB connector I got with MBO on the SAME place, and it works. Why? It's as if the ones on the case were broken, and I doubt they are 'cause the case is brand new, Coolermaster.

USB pin-out is not standardized

The USB pin-out on motherboards is not standardized.
The motherboard maker should supply the pin-out for the USB connector on the motherboard. Or;

Match the "Color Coding" of the bracket that works to the one on the case.
"Standard USB Cable Wiring Color Code"

Please note;
Damage may have already accrued if you plugged in a USB device into the case USB to test the port.
