Weird USB Problem

I just finished putting together a new PC, based around the ASRock P67 Extreme4 Gen3 motherboard. While installing windows, I used the USB 3.0 headers on the front of the case.

Once everything was installed (Windows and all mobo drivers), I went to put the Keyboard/Mouse USB ports into the back, right into the motherboard.

...The computer won't recognize them from the motherboard ports, yet it continues to recognize them from all front ports (all four USB2.0, and two USB3.0 ports).

Any thoughts as to why it won't recognize these devices from the motherboard ports?
