It depends on how easy it would be to add it...
If you can give me the details of the device, I will see what I can do. Where does the device show up under /dev? What baudrate does it need? Are there any serial parameters that it needs that would be considered non-standard? Most importantly, is it using the same AMBE-3000 chip as the ThumbDV? If not, I will probably need to get my hands on a device and the manufacturers documentation. In that case, it would also be nice to start with an already published, working driver. My CDV3000U C++ class driver is based on open-source work by K7VE, NH6Z and G4KLX, so my driver design was the easy part of the qdv development.
