I have developed a simple USB virtual com port (CDC) for a K20 microcontroller. I am currently using my own inf driver file with my own PId/VId.
It works great and I am able to transmit and receive data with ease.
My question is, is there a Pid/Vid combination that will cause any computer to automatically recognize the device as a standard CDC device when it's first plugged in and thus install the appropriate device driver? (I don't want end users to have to manually acquire and install my driver file)
