I need to connect a LPC1769, or a LPC1343, to a PC through USB (to avoid external power supply).
The LPC should enumerates as two CDC (com ports). I found some post related to composite devices, but none for multiple CDC.
Is it possible, and how to do it ? Some source code examples?

Thanks

Angelo

The composite device sample shows you how to define a composite device and how to define a CDC device within it. What else do you need to define a composite device with 2 or 3 CDC devices? Think creative... ;) Just copy the endpoint service routines and make them handle the second CDC device.
