I am concepting a new design that has to communicate using USB.  I have a pivitol question.  Is it possible to implement a USB interface that emulates a PC COM port that will install under Windows without having a device specific '.INF' file?  It looks like a device with a CDC class and an ADM subclass should install, but, it hasn't worked yet.

Also, does anyone know of some example code for a CDC 'USB to Serial' device.  I would like to compare my code with a working example.
