If I understand Matt correctly, he doesn't want what Python USBTMC does. I
believe that's a Python application (which might run on a BB) that accesses
instruments having USBTMC interfaces.

Matt wants to make the Beaglebone one of those instruments. He therefore
needs to have the BB offer a USBTMC device on its device port.

I don't know if such a driver already exists or what would be required to
create one but I would start here :

This explains how to build the kernel with alternate device interfaces such
as MIDI.
