Oct 9 14:40:07 lollybook kernel: [372390.771258] ch341 3-1.4.3:1.0: device disconnected
I found this:
for f in /usr/lib/udev/rules.d/*brltty*.rules; do
sudo ln -s /dev/null "/etc/udev/rules.d/$(basename "$f")"
done
sudo udevadm control --reload-rules
But I also had to disable the brltty-udev.service
$ sudo systemctl stop brltty-udev.service
$ sudo systemctl mask brltty-udev.service
Created symlink /etc/systemd/system/brltty-udev.service → /dev/null.
After disabling brltty I finally got:
Oct 9 14:41:30 lollybook kernel: [372473.985072] ch341 3-1.4.3:1.0: ch341-uart converter detected
