I'm struggling to access an MCU connected to the USB and presented as a serial port: /dev/ttyACM0
. What worked well in Ubuntu 22.04 does not work in 24.04.Whenever I connect the device, the only way to have it access is tochmod 666
it, but that works only temporarily.
The user I'm working on is already added to the dialout
group, and ls -l /dev/ttyACM0
returns: crw-rw---- 1 root dialout 166, 0 Oct 25 15:33 /dev/ttyACM0
, so as I can understand it, it is the root who has r/w and any dialout group member.Am I missing anything here to configure/add?
Regards,
Piotr
