[BRLTTY] brltty usb errors

[Brian Tew]

Hello,
In the last few weeks I have been having a problem with brltty.
The fs focus 40 blue fifth gen stops communicating with ubuntu for a few seconds.
It displays time and percent charge like it does before any connection.
then "brltty 5.6" appears and everything works fine for a while.

the start command is /bin/brltty -e -bfs -ldebug -L/home/btew/log

I grepped out some errors as listed below in hopes they might tell you something.
Any ideas on how to proceed. thanks for your superb program.
