You are right that the device recreates itself every time it is plugged in and the chmod is not persistent. However, I am a member of the dialout group, and that does not give me the required permission to access the /dev/ttyUSB0 device. I don't know why. So far, only the chmod "trick" if you will works, and it is not difficult.

While this will work, it is not really the right way to do it. It is also temporary. These devices recreate themselves every boot, or every time you reinsert a device.
The right way is "sudo adduser user dialout" Substitue your user name for "user." On some systems the group may be different.
Example:
wpmills@suzanne1:~$ ls -l /dev/ttyUSB* crw-rw----+ 1 root dialout 188, 0 Jun 7 18:53 /dev/ttyUSB0 crw-rw----+ 1 root dialout 188, 1 Jun 8 02:49 /dev/ttyUSB1 wpmills@suzanne1:~$
wpmills@suzanne1:~$ sudo adduser wpmills dialout [sudo] password for wpmills: The user `wpmills' is already a member of `dialout'. wpmills@suzanne1:~$

Hi all:
I am not sure who came up with the brilliant tip of chmod 777 /dev/ttyUSB0 as I have deleted the email suggesting that.
So THANK YOU for that suggestion. I was getting frustrated trying to get Chirp on Linux Mint 19.2 to up/download from my new (to me) Icom 2100H. All I got was error messages that the radio had responded inappropriately. Until I did the chmod thing. IT WORKED.
So, thanks again. Now I can get going on the next step of a very long
march.
Peter, VE3BBN
