I get something like this. No results for XHC.

Ok, I reinstalled the OS. I got the keyboard back on now and 2x on left side USB 3.0 works fine as well. USB 2.0 on he right is dead. Camera is OK but microphone is not working. Touchpad seems to not working properly. I have massive problem with CPU/GPU power consumption, the full battery...
