    Intel® USB 3.0 EXtensible Host Controller for Intel Z97 Chipset issue.

    whatcomfalls

      Why are USB 2.0 devices (keyboard. mouse, flash drive) that are plugged into physical 2.0 ports loaded into host controller for USB 3.0?

      Please see attached screen capture.

      Those virtual ports should be filled only if a non-usb 3.0 device is connected to one of the six usb 3.0 ports.
