Yes, I did add my user name to the dialout group.

BTW: The syntax provided at that location is wrong I think.

** Someone at Chirp may want to check this part of docs. ** Actually I guess I should present as a bug report.

It shows "sudo usermod -aG dialout username" which reacts with a command options list, which I think means there is an error in the syntax.

I used "sudo usermod -a -G dialout username" which seems to be accepted.

Didn't change the failure symptom though.

Found my problem... I was making a mistake with case in my user name. When corrected, adding name to dialout group solved problem...

What about if the dialout group wasn't created during setup (I suspect ?)
[marek@marex-x1:~]$ sudo useradd -G dialout "$USERNAME"
useradd: group 'dialout' does not exist

I added the group and reran the command to modify my group membership but still getting:
"[Errno 13] could not open port /dev/ttyUSB0: [Errno 13] Permission denied: '/dev/ttyUSB0'"

yeah sorry for reopening this .
On my Arch I fixed it by adding a group and adding user to it . Later also running sudo chmod 666 /dev/ttyUSB0.
Keep up the good work and thank you!!
