[orca-list] Orca and braille display

[Max <heavy9922 gmail com>]

Hi All.

A user who is not subscribed to this mailing list, turned to me for 
help. He has a Braille display "Focus-40 Blue".
He can not make it work this Braille display, in some distributions of 
linux. This user is trying to connect the Braille display through the 
USB. The distribution "sonar", the Braille display is turned on, and 
then immediately shuts down. In the "fedora" he started, but refuses to 
work.
He also said that when loaded into the live mode, "talking arch", the 
braille display work.
Please tell me, is there a way to make the display work normally?
I unfortunately can not help this user because I do not have a Braille 
display, and no experience to eliminate such problems.
Connecting via Bluetooth does not eliminate the problem.
