Note to people with this issue: If you have multiple controllers TRY DISABLING THE ONE THAT FAILS in Device Manager and testing again.

I ran the rift PC advisor. As I expected it flagged my CPU and GPU. My CPU is a 3770k @ 4.4Ghz though, which destroys the one they recommend as minimum even though it's a generation behind. So that's fine. My GPU is a GTX 670 4GB which when overclocked is about 15% slower than the recommended minimum 970. Yeah it OCs like a beast. But I know it's less than optimal, hope to upgrade before March when my Rift ships.
The main problem is it flagged my USB ports.
Clicking links to a page that says this:
Why am I getting this warning?
If you received this warning message, our compatibility tool detected that some of the hardware that powers your computer's USB ports have known incompatibilities with Rift.
What does this mean?
Rift may not work with your computer's USB 3.0 ports.
How can my ports be incompatible? My mobo is an Asus p8z77-i/wd mini itx. It has plenty of ports so the number is not the problem(I have 8 total USB 3.0 ports, and five 2.0 ports). I REALLY don't wanna have to replace my mobo too. Already gotta replace my GPU.
So yeah, any ideas? Don't be afraid to get technical, I have a degree in computer science and I spend most of my free time doing tech support on PCSX2 forums(it's a PS2 emulator if you didn't know).
