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

[Sebastien Bacher]

Thanks Samuel for sharing your expertise here!

I would need to check why it has been historically installed by default
but I would expect that's because we want the default installation as
friendly as possible to users that need accessibility. Doing what Debian
is doing is nice but gives an inconsistent result since it would depend
of how the system was installed.

We need to discuss what's best going forward but the easiest option
meanwhile for the LTS is probably to disable the udev rule as you
suggested.
