Well, implementing it as UHD device seems a bit overkill from a
programming point of view because one would have to implement the
"audio source", which is readily available in GNU Radio. So a GNU
Radio source just like the old pre-UHD USRP drivers seems to be most
feasible.
Yes, I agree--a UHD driver might be too complicated to do, but maybe
not. Maybe we just have to buy Josh an FCD :-)
I don't know much about the Softrock series, but I doubt they have
much in common with the FCD. Maybe the USB idea and the protocol
structure, which for the FCD is really trivial and simple streams of
1-4 bytes per command. Most of the commands and parameters for the FCD
map directly to the tuner chip, which I assume is not present in the
Softrocks - see attached screenshot of the windows controller.

The SDR-Widget uses a similar approach--a standard UAC2 audio system,
and HID for setting transceiver-specific "stuff".
