Devices do work in the U3. The dock works fine on other PCs w/U3. The dock works fine in U2.
Well that makes no sense, I have no idea what could be going on with the dock. If it work in other USB3 and in USB2, it should work in tour PC if other USB devices work in the 3 ports.
Here is ASRock's support phone, give them a call. 1-909-590-8308
