When plugging in a USB webcam I see the following message: xhci_hcd 0000:04:00.0: WARN Successful completion on short TX: needs XHCI_TRUST_TX_LENGTH quirk? handle_tx_event: 913 callbacks suppressed
All is quiet again with this patch (and I've done a fair but of soak testing with the camera since).

I have been setting this quirk manually for ages on my kernel command line, for the same reason (MS HD Webcam), and with the same positive result, so
