Just recently installed the newest version of ubuntu desktop.

Having issues getting it to see my USB3 ports. if I plug anything into it, it sees nothing.

I have 8 USB 2.0 ports and 4 USB3, two on the back + 2 on the front attached via 1 cable to motherboard.

Not even sure how to tell which one could potentially USB3...

dmesage after plugging / unplugging from USB3 results in nothing.

not sure where to go from here.

LOL. I knew it. See post 16 here: http://ubuntuforums.org/showthread.php?t=2143433

By way of explanation, you took IOMMU control away from the motherboard and gave it over to software control.

Awesome, thanks so much!
