- debian/rules
+ add initramfs integration to run brltty-setup if necessary before
plymouth starts
- debian/control
- debian/initramfs/brltty.sh
- debian/initramfs/hooks/brltty.in
- debian/initramfs/scripts/init-premount/brltty
- debian/initramfs/scripts/init-top/brltty

Braille at install time for a non-USB display
- debian/31brltty
- debian/rules
+ don't install /etc/brltty.conf in the package
- debian/31brltty
+ debian/brltty.udev.rules: don't claim generic USB device IDs it leads
to brltty grabbing serial ports which other devices like Arduinos
boards can't use anymore, thanks Samuel Thibault (lp: #1958224)

Title:
brltty claiming cp210x devices on 22.04
Status in brltty package in Ubuntu:
Fix Released
Status in brltty source package in Jammy:
Confirmed
Status in brltty package in Debian:
Confirmed
Bug description:
* Impact
The brltty udev rules are claiming generic devices IDs which makes
some other devices like Arduino cards not able to interact with the
serial port anymore
* Test Case
Try to use an Arduino over a cp210x or FTDI serial port, it should be
able to talk to the computer
* Regression potential
There are some braille devices on the market using generic IDs which
are going to stop working out of the box. Those devices are uncommon
and it's arguably an hardware bugs they are using those IDs.

Distributor ID: Ubuntu
Description: Ubuntu Jammy Jellyfish (development branch)
Release: 22.04
