The setup packet request type. The request type must specify the IN direction (highest bit set).

request

Type: SystemByte
The setup packet device request.

value

Type: SystemInt32
The value member in the setup packet. Its meaning depends on the request. Value should be between zero and 65535 (0xFFFF).

index
