I have a HDD enclosure that I connect to my laptop via a USB3 port.

Initially the hard disk works fine but then freezes and the following
appears in dmesg:

[  +0.040256] xhci_hcd 0000:00:14.0: WARN Event TRB for slot 4 ep 2 with no TDs 
queued?
[Jun11 11:42] usb 4-3: reset SuperSpeed USB device number 5 using xhci_hcd
[Jun11 11:43] usb 4-3: reset SuperSpeed USB device number 5 using xhci_hcd


This keeps happening.

If I plug the same enclosure into a USB2 port - all is  fine albeit
slower.

It doesn't matter what HDD I have in the enclosure - I get the same
errors.
