This device gives the following error on detection.
xhci_hcd 0000:00:11.0: ERROR Transfer event for disabled endpoint or
incorrect stream ring
The same error is not seen when it is added to unusual_device
list with US_FL_NO_REPORT_OPCODES passed.

Did you ever determine the reason for this ERROR message? Exactly what
is going wrong? Is there a bug in xhci-hcd? Or is it simply a race
