Doug:
A couple of things...
Use your JMRI setup up to look at the list of ports without the USB adapter plugged in and then with it connected see whats new... like ttyUSB0 that's your connection.
But you need to tell the system that you can use the port(s).
From console use sudo adduser "name of computer" dialout
That's the name in the upper left corner of the sign in screen.
You can use lsusb in the console to see USB devices but that doesn't show port number as a tty.
