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. 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. Alex
