Every so often (can be several times in an hour if I'm really unlucky, some days it is less of a problem), the USB hub disconnects from the computer and the devices connected to it lose power and stop responding. disconnecting and reconnecting the USB cables has no effect. I can restore functionality by instructing the xhci_hcd driver to unbind from the USB 3.0 Host Controller in the dock and to rebind to it using the commands: echo -n ":0e:00.0" > /sys/bus/pci/drivers/xhci_hcd/unbind echo -n ":0e:00.0" > /sys/bus/pci/drivers/xhci_hcd/bind Here's the dmesg output when the USB hub disconnects: 279278.102701] xhci_hcd :0e:00.0: ERROR unknown event type 15 [279283.021802] xhci_hcd :0e:00.0: xHCI host not responding to stop endpoint command.
