                    usb_control_in(requestType:requestId:requestValue:index:length:)

Performs a USB control pipe transfer from the device This operation is intended for people familiar with the USB Protocol and assumes that you will do buffer management yourself

Return: The data buffer received from the optional data stage of the control transfer

Declaration

Swift

public func usb_control_in(requestType: Int16, requestId: Int16, requestValue: UInt16, index: UInt16, length: UInt16) throws -> Data

Parameters

`requestType`	bmRequestType; Bitmap specifying the request type in the USB standard
`requestId`	bRequest of setup stage in the USB standard
`requestValue`	wValue param of setup stage in the USB standard
`index`	wIndex parameter of setup stage in the USB standard (typically index of interface or endpoint)
`length`	wLength parameter of setup stage in the USB standard; also specifies the amount of data elements to receive data from optional data stage of the control transfer


                    
                    
                    usb_control_out(requestType:requestId:requestValue:index:length:)

Performs a USB control pipe transfer from the device This operation is intended for people familiar with the USB Protocol and assumes that you will do buffer management yourself

Declaration

Swift

public func usb_control_out(requestType: Int16, requestId: Int16, requestValue: UInt16, index: UInt16, length: UInt16) throws -> Data

Parameters

`requestType`	bmRequestType; Bitmap specifying the request type in the USB standard
`requestId`	bRequest of setup stage in the USB standard
`requestValue`	wValue param of setup stage in the USB standard
`index`	wIndex parameter of setup stage in the USB standard (typically index of interface or endpoint)
`length`	wLength parameter of setup stage in the USB standard; also specifies the size of the data buffer to send from optional data stage of the control transfer
`buffer`	data buffer that sends data from the optional data stage of the control transfer. Ignored if length is 0.

Return Value

The data buffer that sends the data from the optional data stage of the control transfer.
