Uh, it should have been created when running make install. Please create
it and just put arbitrary data in it.

should probably mention it. Dave, here is a patch.

You should also look for the brltty logs in /var/log/daemon.log (or
similar), the following has probably shown up:

Unable to load API authorization key from /etc/brlapi.key: No such
for or directory in brlapiserver_loadAuthKey. You may use parameter
auth=none if you don't want any authorization (dangerous)

I.e. you may just run

brltty -A auth=none -b xw -x no

Dave, maybe the default authentication parameter should include
"user:xyz" where xyz is the uid of brltty?
