Based on your logs, this should do it: echo 0000:00:14.0 > /sys/bus/pci/drivers/xhci_hcd/unbind echo 0000:00:14.0 > /sys/bus/pci/drivers/xhci_hcd/bind Note that if you have a keyboard on this bus it will stop working. You may = want to issue both commands at once: "echo xxxx ; echo yyyy". --=20 You may reply to this email to add a comment.
