New to this site so this may be a dumb question but here it goes. I have a NWDR AMBE thumbdv. Connected to my PC (Win10) and Blue DV installed. I ran the thumbdv test and it is communicating on a com port. I configured BlueDV and started DSTAR. I can receive but can not transmit from my IC9700 which is set for DV operation.
I also have a dvmega on a rpi and that works correctly. You might ask why both - well I bought the Thumbdv last year and am just now seeing what I can use it for.
