The USB Ethernet dongle would look like a network device as far as Roon is concerned, so RAAT would be an appropriate protocol. That said, since @audio_engr has a point-to-point wired Ethernet connection from the Nucleus to the Devialet, RAAT would be running on that link and (I expect) would not be used on the link to the router via the USB-Ethernet dongle.
