UVC 视频控制中断端点描述符

Class-specific VC Interrupt Endpoint Descriptor的前面必须有一个普通的中端端点描述符。

        ----------------- Endpoint Descriptor -----------------
bLength                  : 0x07 (7 bytes)
bDescriptorType          : 0x05 (Endpoint Descriptor)
bEndpointAddress         : 0x83 (Direction=IN EndpointID=3)
bmAttributes             : 0x03 (TransferType=Interrupt)
wMaxPacketSize           : 0x0010
 Bits 15..13             : 0x00 (reserved, must be zero)
 Bits 12..11             : 0x00 (0 additional transactions per microframe -> allows 1..1024 bytes per packet)
 Bits 10..0              : 0x10 (16 bytes per packet)
bInterval                : 0x06 (32 microframes -> 4 ms)
Data (HexDump)           : 07 05 83 03 10 00 06                              .......
