As I said on your original post it would be useful if you would re-flash to FB and see if it still works.
The USB3 controller does not work with FB16 or FB on Windows 7. To get that working, I had to install FC1 which I downloaded from some file site (search), not Gigabyte (why don't they post it?). When I installed FC1, that again broke the Windows 7 Sleep/Resume operation. The mobo won't wake up completely and I have to hard power it off as before. So going from FB16 to FB or FC1 breaks sleep/resume with the same Marvel 9128 SATA3 controller firmware that works with FB16 for sleep/resume. Updating to the Marvell firmware in the BIOS (FC1) does not fix the problem, hence it's likely the FB and FC1 BIOS's that breaks sleep/resume.
On top of this, I've found my Western Digital 1 TB SATA3 HD is only running at 3 Gb/s rather than 6 Gb/s. I have a tech support ticket going on that one with Western Digital.
If you are reading this and considering this mobo based on the Tom's Hardware recommendation (as did I), you really ought to look at other choices.
