public class UsbInterface extends Object implements Parcelable
UsbDevice.
USB devices can have one or more interfaces, each one providing a different
piece of functionality, separate from the other interfaces.
An interface will have one or more UsbEndpoints, which are the
channels by which the host transfers data with the device.
For more information about communicating with USB hardware, read the USB developer guide.
