Some notes on SUSE-specific configuration of brltty
========================================================================

USB:
------------------------------------------------------------------------
Most USB Braille displays should be autodetected by udev, starting brltty.
However, some Braille displays have the same product IDs as generic
USB-to-serial adapters, and, in order to avoid a conflict with these
adapters, the brltty udev rules for them are not installed by default. If
you have an Albatross, Cebra, Hims, HandyTech, or MDV display and connect it
via USB, then you may want to install the brltty-udev-generic package.

Alternatively, you can have systemd automatically start brltty at boot. Run
chkconfig brltty on
as the superuser.


Authentication:
------------------------------------------------------------------------
By default, brltty authenticates with clients (such as orca) via a key
file. However, SUSE enables polkit-based authentication instead.
This eliminates the need to, ie, add users to the brlapi group in order
to be able to have orca interact with the Braille display. It also
disallows remote users from interacting with the display. If you would
like to change this behavior, then you can edit the api-parameters
directive in /etc/brltty.conf.
