Public bug reported:
I'm using a USB hub in the Dell TB16 (240W) connected to a Dell
Precision 5520 using Thunderbolt 3.
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 "0000:0e:00.0" > /sys/bus/pci/drivers/xhci_hcd/unbind
echo -n "0000:0e:00.0" > /sys/bus/pci/drivers/xhci_hcd/bind
Here's the dmesg output when the USB hub disconnects:
