Did you get this working, I am about to start this project. I tried this about 3 years ago and gave up as I could just use the serial port. Any chance you could share your results?

How did you go with this? I am looking into starting a project requiring this exact solution. Can you share your results or give some points as to what steps are required to get it working?

Hi Sadeh,

Have you ensured that Telit he910 is able to operate as standard CDC device without forcefully requiring a custom driver?

I have tested MQX’s CDC Host application with TWR-K70 and a Freescale USB2SER part (DCD device), and communication is properly established. I also tested with another Freescale MCU programmed as CDC device (using MQX or USB Stack) and it also worked properly.
