MIDI Descriptor for USB communication

[towlerg]

You apparently have or have access to a commercial MIDI-to-USB interface. Several USB monitor will generate a descriptor of a connected device (albeit not in exactly PBP format). I have several installed and if you're interested I will see if any for free/trial one will do that.

For example USB Device Tree generates this for a Pickit2
