When 5.11.17 gives me a load of:

What happened?
Either your host is sending spurious events, or more likely this TD (transfer descriptor)
was already handled and given back by driver due some event mid TD.
Host still has this TD cached and generates events for last entry of TD after xhci driver gave it back.
It happened again without me really using USB. (i.e.: no plugging in/out
of USB items)
Does that tell you anything?
The PC has USB keyboard/mouse, but also a connection to the USB hub in
the monitor.
What can I do (to help) fix it?
First try 5.12 (just came out) It has some xhci driver changes in this area.
5.12.6 here...
I'll look into generating a trace.
