So far, like the quad-core Exynos powered Galaxy S III, the new quad-core Exynos powered Samsung Galaxy Note II can work with the FiiO E7, the iBasso D12, Leckerton UHA-6S MKII, the ODAC, … ; had some issue with the HeadAmp Pico (bug fixed by HeadAmp); and doesn’t work with the FiiO E17 using the stock USB audio driver.

So, in regard to the USB protocol, the behaviour of the Galaxy Note II is likely identical to the behaviour of the Galaxy S III.

A list of standard USB DAC reportedly interworking with the Android-powered smartphone Samsung Galaxy S III:

stock Samsung Galaxy S III > digital USB audio out >> USB OTG cable (micro-A plug inserted into the S III) >> standard USB DAC >> amp >> headphones
