System reboots instead of shutting down if xhci is enabled in BIOS and USB hub is connected When I connect the usb hub built into my monitor (http://www.samsung.com/uk/support/model/LS27D85KTSN/XU), the system will reboot instead of shutting down when I do a shut down. If I disable XCHI in the BIOS, the problem does not happen. If I disconnect the hub and enable XHCI, the problem does not occur.
