Hi there,
I'm experiencing a very strange problem with my mainboard and onboard USB ports called USB1112 and USB15 in the manual.

If I connect a Corsair Commander Pro to USB1112, it works fine.
If I connect the 2 USB 3.0 front panel ports (using and adapter) to USB1112, they work fine.
If i connect the CoPro to USB15, iCue only detects the CoPro but does not detect the AIO and the PSU (connected via USB to the CoPro).
If I connect the front panel ports to USB15, only 1 port out of 2 works.

I had to buy a NZXT USB hub to solve the problem, but I had to connect it to USB1112; if connected to USB15, it does not work.

I searched the mobo manual and found (page 17) this hint:
"1xUSB 2.0 port (USB15) at mid-board shares with ROG extension (ROG_EXT) port".

It seems a poor explanation to me... what does USB15 and ROG_EXT port share? I don't have nothing plugged into ROG_EXT port, so why only 1 front panel USB port works? Or this header can only support 1 single USB port?

I'd prefer to usee both headers in their full functionality and get rid of the NZXT hub as the case has narrow spaces and the hub is quite big and carries other 2 cables to fit in the case.

Any idea?
