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

[Hammer Attila]

Hi Dave,

I tested the suspend related reported issue my Ubuntu 14.04 64 bit 
system with BRLTTY latest snapshot release.
I generated an Ubuntu 14.04 compatible package from following 
repository, possible this is the problem:
git://anonscm.debian.org/pkg-a11y/brltty.git
When I wakeup my machine from suspend, in my braille display I seeing 
graphic session with "Screen not in text mode" text until I not turn off 
and turn back my braille display. I have got an Alva Satellite 570 
braille display, I using my braille display with my display USB port.
Have possibility to BRLTTY lost the connection after wake up from 
suspend with Alva displays?
I attaching monday a new log file?
Reproducation steps with Alva satellite display related, I using Ubuntu 
14.04.1 64 bit version:
1. When working right in Orca the braille output the graphic session, 
suspend the system.
2. Wait few seconds, and wake up the system from suspend.
Expected result after wakeup from suspend:
In the braille display need presenting the password dialog related edit box.
Actual result my display: I see "Screen not in text mode" text. After I 
typed my password and  I turn off and turn on my braille display I see 
again the braille outputs.
This test passed right oldest time with BRLTTY 4.5 release without any 
problems, the connection is not losted after wakeup from suspend.
