Unless the above is a typo, it's saying that you're writing the log into 
brltty's configuration file.

It must be starting too early.

We had a case where brltty was starting too early, and this is what we now 
specify:

   DefaultDependencies=no
   After=local-fs.target
   Before=sysinit.target
   Wants=systemd-udev-settle.service
   After=systemd-udev-settle.service

>Logs are below.

That log is indeed vague. Are you able to rebuild your brltty if I send you a 
patch to one of its source files?
