Parameters

requestType

A bitmap field for defining the USB control port request. The bitmap fields are defined by the USB specification. The direction bit must be device-to-host.

request

Request ID for this transfer. The meaning of this value depends on requestType.

value

The requested value for this transfer.

index

The interface or endpoint index number, depending on requestType.

length

The length of the data in bytes to send to the device during the Data stage. If this value is 0, then a zero-length byte array is returned from this method.

Return Value

The usage of each parameter is based on the relevant USB base or class specification, or on a vendor-specific request definition.
