Troubleshooting

Problem:

Tried to hook up usb but it got disconnected with following message from dmseg:

[Tue Mar 12 15:14:58 2024] usb 1-2: usbfs: interface 0 claimed by ch341 while 'brltty' sets config #1

Solution: Executed command

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
sudo systemctl mask brltty.path

Without need of reboot, everything worked fine, device appeared on /dev/ttyUSB0 path
