Just a made up term.  I was trying to refer to brltty being started by
udev.

It should be.  I have never tried.

What would happen if you disconnect both devices and reconnect them both
again, without starting/stopping any daemons?  Will udev fire up two new
brltty processes, in addition to the already running one?
Do you see what I am trying to get at?  This has quite some potential to
leave behind a mess.
