what are the difference between USB Audio Class 2.0 and new USB 3 that we can find on new macs.
USB 3.0 refers to the bus itself, whereas USB Audio Class 2.0 defines a specific type of device that can be connected on the bus. These are independent specifications. That is, a USB audio class 2.0 device can operate on a USB 2 or USB 3 bus. As far as I know, USB 3 in itself doesn't directly affect the USB audio class specifications.
One of the things that the USB organisation has tried hard to do, and largely succeeded, I think, is to maintain backward compatibility so that equipment defined against older specifications can be used with later equipment using newer specifications. A big part of this is the way devices can advertise their capabilities to a host when they're first connected (part of the so-called "enumeration" process).
