I found this thread accidentally and got interested in it
so here are my two Cents worth.
When you run a program or application, that application
may need kernel modules that aren't part of the kernel right now
so it looks in a special directory which is
/lib/modules/long_number. In my case, long_number is
4.9.0-6-686-pae
Yours could be the same or more likely, it will be
different and you find that out with the command
uname -r
The output you get from uname -r is what you put after
/lib/modules/
Your modules directory might have a module supporting
brltty and you can find that out by cd
/lib/modules/that_long_number and then doing ls |grep -i brltty.
What that does is list all the files in the directory and
only print those containing brltty in their name and it won't
matter if the brltty is all upper case, lower case or some crazy
mixture.
If nothing is there, you have no brltty modules so you
have found the bottom of that rabbit hole and don't need to dig
any further.
If you do, however, then lookup how to keep your computer
from using that module since you don't need brltty anyway. That
procedure is different with different versions of Linux so read
how your version blacklists kernel modules to keep them from ever
loading.
This is one of the many things about unix that are really
useful since you can tweak your system to fix seemingly
intractable problems at times.
