[BRLTTY] Interesting issue with brailliant 40

[Tom Masterson]

I am using ubuntu 20.04 LTS, and a brailliant 40 via usb.  If I disconnect 
my display to use it with my iphone or another computer and then reconnect 
it later brltty does not always bring up the display.  Sometimes I an get 
it up and running by hitting a key on the keyboard and sometimes it 
requires a reboot.  If I try using systemctl to restart brltty it works at 
the console but not in orca and a ps -A shows 2 copies of brltty running. 
As I tend to spend more time at the console than in the desktop it is not 
a complete show stopper but as we all know there are occasions when we 
must use a desktop (like to get to firefox to browse some pages that don't 
work in lynx) and I really dislike using speech exclusively.  The version 
of brltty is 6.0 and all of this worked under ubuntu 18.04.

Any ideas of why brltty is not recognizing my display when I reattach it?
