Run thumbtest.exe inside a cmd window -- e.g. go to run, and put cmd in, then run thumbtest.exe
A little explanation of how this all works may help with your debugging.
ThumbDV™ is an AMBE 3000 chip attached to an FTDI USB to serial chip. All of the communication into and out of the AMBE chip is serial data, a stream of serial bytes. If you send it 8kbit encoded audio, it sends back AMBE, if you send it AMBE, it sends back 8kbit encoded audio.
FTDI chip is responsible for sending the serial data back and forth over a pseudo-serial USB port (COMx).
BlueDV and similar programs are responsible for sending and receiving the serial data streams to the ThumbDV over the USB serial port, and control communication to audio input and output to the operating system (Windows in this case), which delivers it to the speakers and receives it from the microphone.
Furthermore, BlueDV can send and receive AMBE over the network to other providers/consumers of AMBE data, such as reflectors, hotspots, and gateways. Again, BlueDV does the routing to/from the ThumbDV™.
The ThumbDV™ again does none of the work to deliver either audio or AMBE to either the speakers/microphone or network directly. It only is a serial device attached to a USB com port.
Once you have confirmed that data is going into and coming out of the ThumbDV™ via the ThumbTest.exe, LEDs on the ThumbDV™, and/or other programs, then troubleshooting is in the configuration of your application such as BlueDV, or the operating system such as Windows.
Ensure that network ports are available to the application, and that the FTDI driver is working between the operating system and the ThumbDV™.
