I have looked high and low....... Is there a motherboard at any price or any socket, that comes with two onboard USB 3.0 headers?
I'm at a loss as to how they expect you to connect a card reader that's only power source is a 20 pin USB 3.0 connector, when there is only one on the board and every case known to man these days has to have one to power the USB 3.0 ports in the front of the case!
