[Bug 1958224] Re: brltty claiming cp210x devices on 22.04

[Sebastien Bacher]

Thanks Samuel, I've uploaded the changes now.

I also checked a bit the package history since I'm not really familiar
with the package (we used to have Luke working on accessibility but
since he left we mostly carried the status over and don't have anyone
really familiar those changes) and it seems I was wrong in what I wrote
on the installer


The intend seems to be that brltty is always installed but the installer writes a /etc/default/brltty configuration and the systemd units should be active depending on the configuration (which is a delta we carry for brltty)
