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.
