Yes it does. When (re-)starting the scan application the second time
the code hits xhci_endpoint_reset
if (!virt_ep->stopped_td) {
xhci_dbg_trace(xhci, trace_xhci_dbg_reset_ep,
"reset not halted endpoint 0x%x",
ep->desc.bEndpointAddress);
ret = xhci_reset_not_halted_ep(xhci, udev, ep);
...
[15877.581997] xhci_hcd 0000:00:14.0: reset not halted endpoint 0x81
