I think with Bookworm you should have BRLTTY 6.7. I have the following line in the brltty.conf. braile-device ttyUSB0 This works for Alva connected to a USB serial converter.

Dear List, Unfortunatelly, possible my old Alva display are defected, so I tryed my another home have Focus 1 70 display. Normal serial cable and normal serial 9 pin port the display work, but my second machine not have a general serial pin cable hardvare connector, so I buied a Genbird USB to serial 9 pin cable. Both Ubuntu 20.04 and Debian 12 are correct detected my usb to serial cable, and created correct the /dev/ttyACM0 device. In /etc/brltty.conf file I set braille driver related config key, and added following line into the config file: braille-device serial:ttyACM0 # First serial device. Because the display shows only the focus 70 related status message and not the actual braille output, I restarted BRLTTY with sudo brltty -d /dev/ttyACM0 and -D fs command, and used the -L option. I translated the possible relevant log file entries from hungarian to english with Google translator, but I don't what means the missing libraryes related error messages, and how possible correcting these issues. The log file is created In Ubuntu 20.04 Mate edition, with Brltty 6.5 revision. If need, I have possibility to create a log file my test machine the Debian 12 Bookworm release, I not remember BRLTTY come my system from the backport repo or not.
