[BRLTTY] Brltty doesn't resume back after wakeup from suspend

[Hammer Attila]

Hi Dave,

I think happened my system a large corruption with BRLTTY related.
Now BRLTTY doesn't probe my Alva Satelite display when I booting with 
Ubuntu 14.04.
If I goto my old Ubuntu 12.04 system, BRLTTY fine probing my display, so 
the display is not bad.
I already try remove /var/lib/brltty/brltty.prefs, /etc/brltty.conf, but 
this is not resolve this last problem.

If I looked the reported issue a clean system, I reporting back to you 
the result.
