[BRLTTY] more symptoms (was Re: Kernel 2.6.21 USB issues)

[Jason White]

It appears that the beeping of the display only happens while BRLTTY is
active, and (presumably) searching for it.

If I power off the display while BRLTTY is running, within a few seconds
the display gets powered back up and returns to the configuration menu in the
firmware, then starts beeping again. BRLTTY doesn't find it, but evidently
keeps trying until killed.
