Dmesg didn't show errors related to usb, graphics on the other hand had some issues. The xhci driver found the USB3 ports, (6 of them, this is what the controller supports, not actual physical ports) USB3 devices support USB2 speeds, if the USB3 link training fail then USB2 speed will be used. The link training is automatically done by xhci hardware. The devices were using the xhci driver and controller but at usb2 speeds. Does the USB3 devices work as USB3 on other machines? Any extension cable or docking station in use? are they working, and USB3? Can you see the Additional USB 3 pins in the host port. How about if you reboot with a USB 3 device connected, does it still show up as USB 2 device? (Trying to avoid powermanagement from impacting this) -Mathias
