Motherboard USB 3.0 header question

Hi, I have the ASRock Z87 Extreme9 a/c but this questions applies to any motherboard, I suppose.

The Extreme9 comes with a WLAN that occupies a front drive bay. It also has 4 x USB 3.0 ports and a single SD card hole.

However, there is only one lead to the USB 3.0 header on the board. I have read that USB 3.0 headers can only ever manage 2 x USB 3.0 sockets.

My question is to ask whether only two of the panel USB sockets will work?

  1. USB Header is for the front USB port on the case and the 4x USB 3.0 are on the back I\O panel. Controlled differently. So you have 1 front usb from the USB header and 4 back usb from back I/O.
  2. Thanks for responding, but I didn't make myself clear.

    1. The board has 6 x USB 3.0 slots on the back I/O
    2. The WLAN unit in the front 5.25" drive bay adds another 4 USB 3.0
    3. My Arc Midi R2 case adds another 2 x USB 3.0

    Total of 12 and yeah I know, I'll never use them all!!

    So the 6 USB 3.0 ports on the back I/O, are OK and will work, no probs.

    The issue is about the 4 x USB 3.0 on the 5.25" front bay WLAN unit and the 2 USB 3.0 on the case.

    As I said, the board has 2 x USB 3.0 headers
    The Case has one USB 3.0 connector cable for 2 USB 3.0. Should be OK.
    The WLAN bay unit has ONLY ONE USB 3.0 connector cable for 4 x USB 3.0. Can all 4 work off one cable? Why fit 4 if not???

    Bit puzzled.

    Thanks very much
