Nut upsdev - Mar 2023 - Free and well documented NUT driver protocol

Hello there,
I am coming to this mailing list as suggested in the Github repo issues 
panel: 
https://github.com/networkupstools/nut/issues/1873#issuecomment-1475408950

I would like to create a new UPS device that communicate with the outer 
world over USB. The USB protocol can be either CDC serial or HID. I am 
looking for an existing protocol that can be legally used by me, so I 
don't need to come up with a new protocol + ask anyone to add any new 
code to the NUT project. It should also be well documented, since I need 
to reimplement it in my device.

What would be the best approach here? I would appreciate all help and 
feedback!

Many of the HID-based UPS use the Power Device Class, docs are at
