I imagine your setup is going to be a bit of a hybrid but it's strange that if you're running Xubuntu, it's not using the usual "dialout" group. A long time ago, it was the "uucp" or "cu" groups to get you serial access.

I think it's Xubuntu 16.04 but it's running as a CHROOT on top of Chrome OS using Chrome's kernel for hardware access.
Installed using the Crouton scripts. 
I haven't yet looked at FLDIGI with my Navigator interface to see which groups it's 6 USB ports fall into.

Good point. dialout was the defacto standard for so long that us long term
*NX people still go by it. It's like saying I'm going to tape something on
my DVR. I guess now that modems and serial interfaces are legacy items on
most computers it would make sense for the newer distros to make them
separate. I'm actually glad you made this post. I have a script I use to
install the FLdigi suite and other apps on new computers and I didn't
include adding the user to required group.

Can I ask which distro you are using?

Didn't work for me. My system allocates /div/ttyUSBx to the "serial" group
so if you cannot access your USB/serial
ports, check permissions for the /dev/ttyUSBx device to see which group
it's a member of.
