Good day, I'm testing the new 3.2.2 version of Desktop and attempting to read/write to a device through a serial port ( /dev/ttyUSB0).
I'm testing with "picocom" but will be using my own code in the future.
When running under the guest account i receive the following error:

picocom -b 115200 -recei /dev/ttyUSB0

FATAL: cannot lock /dev/ttyUSB0: Permission denied

guest is in groups uucp and dialout

Any help will be appreciated !
