I have the latest Intel USB 3.0 driver installed. The back ports work fine. When I plug the Corsair front panel into the back ports of the motherboard there is no recognition in Windows of the HDD being connected at all. So there's something wrong with the front panel too. I'm about to just give up on the front panel ports and internal headers, and just use the back ports. Really frustrating, I have these features and being able to use them would be nice.
On my system, all 3 headers are in use (one to MB case, one using GB bracket, one on a rear bracket). All three are working fine under Windows 7 (BIOS F9d). Checking the Device Manager, for USB 3.0, I have 4 entries:
Intel(R) USB 3.0 eXtensible Host Controller
Intel(R) USB 3.0 Root Hub
USB 3.0 Hub
USB 3.0 Hub
The eXtensible host controller and the two 3.0 hubs list the driver version: 126.96.36.199.
The two 3.0 hubs, under the Power Management tab, have "Allow the computer to turn off this device to save power" unchecked. (I don't know if this might matter. I seem to remember reading something about a Power Management issue for some USB 3.0 configurations (not related to GB boards though). I don't remember unchecking it, but I must have done at some point.
Could the problem be in part a flaky USB device? My Corsair Flash Voyager GT 3,0 doesn't always work on a system in my office where my WD My Book 3.0 works fine. Do you have another USB 3.0 device to test?
