Two different USB 30 headers

mlane49 · Sep 12, 2013

I am putting an HP M3970AM-HP (Angelica2) motherboard in a Corsair C70 case. I understand that this motherboard is made by GIGABYTE.

The problem is that the front two USB 30 connectors combine down to a 20 pin header. The case header fits the motherboard but USB's don't work.

I have heard that Gigabyte has its own pin layout that is different from everyone else.

If so what is the best way to get around this?

Thanks in advance
Mike

The 20 pin USB header is a standard header. I would recommend you make sure that the ports are fully seated and that you have the right drivers installed.

The old front USB 30 cable works fine. I cannot swap cables since it is too short. I would have to do some rewiring. I have tried two separate USB 30 cables from Corsair and both fail. It sure looks like a in mismatch.

If they have a different layout, then they can hardly call it USB anymore it's supposed to be a universal serial bus...see if there's a setting for it in your bios maybe?

did you install the 20 pin upside down? If you did that the first time and shorted the USB 3.0 controller, you may be SoL.

The header is actually 19 pin and Keyed.
