USBDeviceControlIn Method (Byte, Byte, Int32, Int32, Byte)

Initiates a control transfer over the default control endpoint. The request should have an IN direction (specified by the highest bit of the requestType parameter). The length of buffer given by the buffer parameter will dictate the number of bytes that are transfered and the value of the setup packet's length member.

Copy

public int ControlIn(
	byte requestType,
	byte request,
	int value,
	int index,
	byte[] buffer
)

Public Function ControlIn ( 
	requestType As Byte,
	request As Byte,
	value As Integer,
	index As Integer,
	buffer As Byte()
) As Integer

public:
int ControlIn(
	unsigned char requestType, 
	unsigned char request, 
	int value, 
	int index, 
	array<unsigned char>^ buffer
)

Parameters

requestType: Type: SystemByte
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: Type: SystemInt32
The index member in the setup packet. Its meaning depends on the request. Index should be between zero and 65535 (0xFFFF).
buffer: Type: SystemByte
The buffer that will receive the data transfered. The length of this buffer will be the number of bytes transfered.

Return Value

Type: Int32
The number of bytes received from the device.
