Unless it is not in group dialout, it should work. Only other thing I can think is check dialout in with both "sudo vigr" and "sudo vigr -s" and make sure both dialout listings show your username. "vigr" stands for "vi" and "group", "vi" the editor however first time you use "vigr" you should be able to set for a different editor if you don't like "vi"

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:~$
