As far as I can tell, that works. Turning the UA-1000 off and on works
very nicely without any problems, as does unplugging the USB and
plugging it in again (usually [*]).
I didn't test the case where a few URBs get a status of -EPROTO but the
USB then recovers: I was naively hoping to achieve this by quickly
unplugging and replugging the USB cable, but then I realised that I'd
have to be very quick indeed. I did think of stringing together as many
of the worst quality USB extension leads I could find until I start to
see errors: I might try that tomorrow, unless anyone can suggest a
better idea.

[*] I did once get an "Unable to handle kernel paging request at virtual
address 000156cc" oops when I unplugged the USB cable and then
immediately plugged it back in again with jackd running realtime, and
also once managed to freeze the computer by doing this, but I wasn't
able to reproduce either case, and I'm fairly certain it was jackd
getting itself in a knot, and nothing to do with the patch you sent.
