java.lang.Objectch.ntb.usb.Usb_Descriptor
ch.ntb.usb.Usb_Interface_Descriptor
public class Usb_Interface_Descriptor
Represents the descriptor of a USB interface.
The interface descriptor could be seen as a header or grouping of the
endpoints into a functional group performing a single feature of the device.
The length of the interface descriptor is
Usb_Descriptor.USB_DT_INTERFACE_SIZE
and the type is
Usb_Descriptor.USB_DT_INTERFACE
.
