Jason,

I will turn on the logging as you suggested. I may have an option for an actual physical machine to test it on later this week.

I've just tested a Focus 40 Blue display here with BRLTTY 5.2 running under Arch Linux x86-64. The pan right key behaves exactly as expected.

Note that I am running Linux directly on hardware, not in a vm. I don't know whether this accounts for the difference though.

I would suggest turning on the logging options of BRLTTY (there's a command line parameter that will capture all of the braille display protocol packets).
Then post a query to the BRLTTY mailing list (brltty@mielke.cc).
Alternatively, you could create a Debian bug report and one of the Debian developers on the list could forward it.

Are you in a position to test a similar configuration without a vm involved?
