You need to be a member of the dialout group to access the USB port.

As you've noticed, the /dev/ttyUSB0 device has the group of dialout. All you need to do is add the second user to the dialout group:

sudo adduser second_user dialout

second_user will need to log out & log back in again for this to take effect.

Just installed CHIRP-daily 20210429 to use with my Yaesu FTM3207D (FTM-3200D on menu).

When connecting the radio to the laptop (Linux Ubuntu 20.04) and starting CLONE I keep on receiving an error message errno-13 regardless of which ttysx I select. It also tells me permission denied. And so no connection made.

Which permission needs changing and how please? There's no provision for that within the CHIRP software, that I can see.

If its a Linux permission for the software (which I doubt), then why does the CHIRP software function in other respects?

Help would be appreciated, please?

Thanks and 73,
