cp210x converter now disconnected from ttyUSB0 by 'brltty', on Ubuntu MATE 22.04 LTS.

Recently, I install CircuitPython on ESP32-S3-DevKitC-1 on Ubuntu MATE 22.04 LTS/VirtualBox. But the CP2102N USB to UART Bridge Controller always attached and disconnected, like this:


It's found that the interface 0 claimed by cp210x while 'brltty' sets config.

BRLTTY is a background process (daemon) which provides access to the Linux/Unix console (when in text mode) for a blind person using a refreshable braille display. It drives the braille display, and provides complete screen review functionality. Some speech capability has also been incorporated.

In my own case, I think brltty is not needed, so I remove it with command:
sudo apt remove brltty
It work for me, ttyUSB0 can be connected normally after brltty removed.
