You'll have to clarify what you mean by "didn't recognize it". You don't get device control with a USB mass storage device. USB mass storage only allows you to access whatever media you have stored on the device's media card. It does not function as an audio out for USB mass storage devices such as your Android device. iPods are certainly different as they have an interface designed for control and audio. Android has no such standard interface.
I don't have a 2012. What does the manual say?
