Description
Size of this descriptor in bytes
INTERFACE Descriptor Type
Number of interface.
Value used to select alternate setting for
the interface identified in the prior field
Number of endpoints used by this
interface (excluding endpoint zero).
Class code (assigned by the USB).
Subclass code (assigned by the USB).
Protocol code (assigned by the USB).
This field is set to FFH, so the device
uses a vendor-specific protocol for this
interface.
Index of string descriptor describing this
interface (no string defined)
