Makes sense, thanks for pointing that out. I'll send the logs and the
xHCI trace as soon as I capture one, and I will treat it as a separate
issue from this patch.

Yes, I saw these hangs before 7.3 as well, so I do not think it is a
7.3 regression. I have no logs from those earlier occurrences, so I
can only vouch for the symptom (the device drops off the bus and the
hang needs a reboot), not that it is the same code path.

Scarlett also likes to reset/disconnect with -71 and -110 errors fairly
often. The kernel generally re-enumerates it, but once in a while I do
see the disconnect get stuck.
