The group membership looks good.  But, just to be sure, did you log out and back in after adding yourself to the 'dialout' group?

It won't take effect unless you've logged out and back in.

Thank for your help.

ls -l /dev/ttyUSB0 (as my regular user)

crw-rw—— 1 root dialout 188, 0 Mar 22 00:21 /dev/ttyUSB0

groups

sam adm dialout cdrom sudo dip plugdev lpadmin sambashare

thx, sam kk4jzh

Sam,

Please do this:

ls -l /dev/ttyUSB0

Send back the output.

Also send back the output of this when you are using your user (regular)
account:

groups

It is important that you are in the group that owns /dev/ttyUSB0

I'm not using Ubuntu but Arch Linux, but here is my output to show you:

ls -l /dev/ttyUSB0
crw-rw---- 1 root *uucp* 188, 0 Mar 21 09:40 /dev/ttyUSB0

[djringjr@n1ea ~]$ groups
video *uucp* wheel djringjr

I've made *uucp *bold so you can see the important part.

I believe /dev/ttyUSB0 in Ubuntu is owned by root tty - don't change it!
Just make sure you are a member of whatever group that owns /dev/ttyUSB0.

Different distros handle devices slightly differently.  The point is that
if you are executing CHIRP and you are not a member of the group that owns
the /dev/ttyUSB0 device, it will not work.

To add a user to a group - whatever group owns the ttyUSB0 -

sudo adduser user group

Where user is your user name and group is the group that owns ttyUSB0
