I'm using ASF4/START with a current project that includes USB and the CDC class setup as a single virtual comm port. All is well.
I'd like to modify my project by dumping the separate old school RS-232 serial debug port and create a second virtual comm port over the existing USB connection as the new debug port. This way there is a single cable from my equipment to the PC, with the application talking on one USB virtual comm port, and debug messages going out to a second virtual comm port.
Long story short, I can't seem to select two CDC's with ASF4/START. Am I missing something? Or is it not supported under ASF4/START? I've seen references in other posts with presumably ASF3 and multiple CDC's so I know it's possible with the hardware.
Can one of you gurus help me out and point me in the right direction? What's the easiest way to move up to two or more CDC's with ASF4?
