--- Comment #2 from Stuart Hayhurst (stuart.a.hayhurst@gmail.com) ---
I had another go at troubleshooting, disabling ASPM doesn't seem to help.

If I can get a device connected without the controller giving up, when I unplug
it I get:
```
[  243.504068] xhci_hcd 0000:77:00.0: WARN Set TR Deq Ptr cmd failed due to
incorrect slot or ep state.
```

When I shut the computer down, if the controller hasn't already given up I see
the previously mentioned warning about command timeouts. Sometimes it throws it
when plugging a device in, but this isn't as reliable.

I tested it on Windows 11, and everything seems to work flawlessly.
