<div dir="ltr">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.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Jun 8, 2020 at 12:59 AM W Paul Mills <<a href="mailto:ac0hy@wpmills.com">ac0hy@wpmills.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">While this will work, it is not really the right way to do it.

also temporary. These devices recreate themselves every boot, or every <br>

<br>
The right way is "sudo adduser user dialout" Substitue your user name <br>
for "user." On some systems the group may be different.<br>
<br>
Example:<br>
<br>
<br>
wpmills@suzanne1:~$ ls -l /dev/ttyUSB*<br>
crw-rw----+ 1 root dialout 188, 0 Jun 7 18:53 /dev/ttyUSB0<br>
crw-rw----+ 1 root dialout 188, 1 Jun 8 02:49 /dev/ttyUSB1<br>
wpmills@suzanne1:~$<br>
<br>
wpmills@suzanne1:~$ sudo adduser wpmills dialout<br>
[sudo] password for wpmills:<br>
The user `wpmills' is already a member of `dialout'.<br>
wpmills@suzanne1:~$<br>
