Problem in USB Communication

, ,

HI,
I am using colibri T20 V1.2 A (CE7) with career board. I have developed Smart Device application in C#. I want to establish USB communication between colibri board and controller device(which is connected to colibri board with USB cable ). I want to read bytes sent from controller in c# smart device application which is installed on colibri board and to write bytes and send to controller.
How should I implement this? Best regards.

There are different approaches you can handle that. I think a good starting point to get an overview is the following blog entry on our side about communicating over USB with your WinCE device: https://www.toradex.com/blog/usb-tete-a-tete-with-embedded-device
