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
