Byte length of this descriptor
Interface Descriptor type
Number of interface.
Value used to select an alternate setting for the
interface identified in prior field
Number of endpoints used by this interface (excluding
endpoint 0) that are CSM dependent
Must be set to zero
Must be set to zero
Index of a string descriptor that describes this Interface
Byte length of this descriptor
channel descriptor type
Number of the channel, must be a zero based value
that is unique across the device
Bits(7:5)
Must be set to 0.
Bit (4:0)
0 = Not used
1 = Interface
2 = Endpoint
3...31 = Reserved values
Identifier of the target recipient
If Recipient type field of bmAttributes = 1 then
bRecipient field is the bInterfaceNumber
If Recipient type field of bmAttributes = 2 then
bRecipient field is an endpoint address, where:
D7: Direction (0 = Out, 1 = IN)
D6...D4: reserved and set to zero
D3...D0: Endpoint number
alternate setting for the interface to which this channel
applies
