"I have had no chance to have a listen yet (got mine yesterday), can only report that my Pico is NOT working with it. Although I kinda expected that, as it doesn't work with the Int S3 either, I'm still pretty gutted (I could use a powered USB hub I guess, but that is just way too unwieldy for me to contemplate)."
So, in regard to standard USB audio, the behaviour of the Galaxy Note 2 is likely identical to the behaviour of the Galaxy S3.

I may have to start doing some reading :)
A list of USB DAC reportedly interworking with the Galaxy S3 can be found at the following link:
