Ok, lsusb is helping. If I plug into the "device" port on the launchpad
*nothing* shows up. If I plug into the "debug" port it shows up as
dev1.7. This is on the same port that was showing a mouse as dev1.6.
But this is a start. I guess I was using the wrong port on the launchpad.

I appreciate the help, but I don't understand much of this. Like I've
said, I'm a complete noob at Linux. Do I need to do any of this? There
is only one user, "raspberry".

But only if the devices are connected in the same order each time. I
noticed that when the mouse is plugged in it was port 1.6. When I
unplug it and use that port for the launchpad it becomes port 1.7. Is
that expected?

It may be my friend, but I can't figure out how to run it... Is that
what friends are about, hard to understand? I also can't figure out how
to run miniterm. Google searches... or more accurately a duckduckgo
search on miniterm I get all manner of links to pyserial and few, if
any, to miniterm. The noob factor is at work. I can download what
seems to be pyserial, but I can't figure out how to run it as an
application.
