quoting Dave: Look in /usr/lib/systemd/system for a file with a name like brltty.service. In it, look for a line that starts with ExecStart=. It's probably specifying /bin/brltty
(end of quote) /usr/lib/systemd/system does not exist. /usr/lib/systemd does exist, but theres no system directory in it. locate brltty.service done as root gives four listings; /etc/systemd/system/sysinit.target.wants/brltty.service /lib/systemd/system/brltty.service /var/lib/systemd/deb-systemd-helper-enabled/brltty.service.dsh-also /var/lib/systemd/deb-systemd-helper-enabled/sysinit.target.wants/brltty.service but even though the locate command shows them root cannot see three of them. When root tries to edit those files it says no such file or directory. Only the second one can be found by root. /lib/systemd/system/brltty.service that file is below. the execstart line is not so simple.
