Idea just came out of my mind. I want to make some kind of USB speaker application using AT90USBKey - AT90USB1287. I know there are many direct USB audio chip (sound card) on the market (eg:PCM2704). I'm just curious about the implementation. Is it possible to implement this kind of USB class using AT90USB1287?
I have another idea. Is it possible to implement USB host using AT90USB1287 to control USB audio chip above (PCM2704)? This makes AT90USB1287 must be an USB audio speaker host.
