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. lsusb gives me this. 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.
