Very likely the Android device doesn't advertise any particular USB spec. If anything it might have a logo for the minimum spec it supports. You can put USB controllers in a device and not worry about any USB-IF if you don't use any USB branding on the box, IIRC any licenses owed are covered in the price of the ICs. The logical connection in USB doesn't care about the physical connection. Your phone could just have some soldered leads for all the protocol cares.
