Ubuntu 22.04 Jammy Jellyfish LTS breaks USB serial

However, I see permission denied for Adafruit M0 (SAMD) which uses /dev/ttyACM0.

When you “for fun” run sudo pio device monitor in the CLI is it able to access the device?

Then the USB serial failed on Ubuntu and Manjaro… Perhaps there were kernel changes.

I’ve seen that one before in BluePill stm32f103c8t6 USBSerial issues - #15 by thk.
