So after some Googling it seems I'm not the only one having this problem! I did the latest BIOS update and I'm still having these problems with the VIA USB 3.0 Headers / Hubs on the motherboard (only tested the ports connected to the motherboard itself so far):
(Note: Of course, I'm using an Ivy Bridge processor)
- No matter what driver I install (off CD or VIA's website), Windows 7 64-bit always has an exclamation point over it for "VIA USB 3.0 Root Hub"
- The ports have never worked, even with the drivers installed and even with devices hooked up to the two Intel USB 3.0 ports.
- This system now has BSODs associated with USB, FE and C2. It didn't have these BSODs before with my old X58 setup, even though I didn't do a fresh install of Windows (and I'm not going to do this, I keep multiple images and file backups to avoid doing this). It especially gets BSODs if it tries to enter sleep mode, which I know is a problem with some USB drivers.
- My BIOS was flashed to the latest available so far (F17), which did seem to reduce the BSODs.
I bought a "Pluggable" 10-port USB 2.0 external Hub off of Amazon, seeing it has great reviews, to use all my USB 2.0 devices so I don't have to use the VIA ports at all. It seems they're still rather unstable, as well as dug out some USB 2.0 slot headers. I'll probably be buying an *external* USB 3.0 hub in the future.
