No thank you. If your device is showing up on /dev/ttyUSB0 but not being opened by qdv, then I think that means that it is not a fully compatible clone of an AMBE-3000 device. Without either a white paper describing the software interface (like the one DVSI published), or an open-source example to go from, I'm not going to invest any time on this. Trying to figure out what the differences are by trial-and-error is not something I want to do.
I have asked to join Team6160 on July 22 but there has been no response yet.
