x370 Killer SLI/ac Front USB doesn't work properly

Hi folks,
I have an X370 Killer SLI/ac with a Corsair case that has front-panel USB 3.0 (2 ports, one internal connector). After connecting the front-panel up to the motherboard, I find that one USB port works, and the other doesn't.
I even RMAed the front-panel from the manufacturer and reinstalled it, but I still find that one USB port works and the other doesn't.

So it sounds like it's a motherboard issue, right? What could it be?

Thanks,
Michael

Same MB here.

Where is it you are plugging it in at on the MB?

I have both mine connected in the middle of the board, above the SATA ports.

EDIT:

One works? You mean to say one port of the two off the same USB case connector?

that sounds more like front panel issue if both mobo ports acting same way
feel free to rma again or test in in another pc
or maybe your usb device doesnt sit in properly?

Lemme guess. When connected to either USB 3.0 port on the MB it is the same case port that does not function. correct?

If so, that's telling me the front panel you've been getting is wired incorrectly, or defective.

I assume, since I haven't read you say it, that on both MB ports the same panel USB port doesn't work.

If that's the instance here, then yea. I am.

Isn't that pretty unlikely? Yes and no. IMO, that would point to the panel not the MB. I've received staranger oddities that caused me to lose hair over.

so............

When connected to either MB connection. Does the same panel USB port not work?
