The sequence should go like this: - The host sends the Set Interface command that enables the isoc endpoint.
So, is it necessary to have a different alternate setting for isoc transfer? Is Set Interface mandatory to start isoc?
Is it that, there can not be asynchronous isoc transfer? Host sends IN token. Core receives it, sends 0 packet to host, generates xfernotready to SW, gadget is not ready to send data now. Host is still sending IN token and receives 0 byte packet. Gadget becomes ready after an *undefined* time. Now it does not have track of micro frame number.
