Transfer(Byte, Byte, UInt16, UInt16, Byte[], UInt16, UInt32)

Performs a control transaction on the endpoint, zero for this device.

Declaration

                    Copy
                    
                
            
public int Transfer(byte requestType, byte request, ushort value, ushort index, byte[] data, ushort length, uint timeout)

Parameters

Type	Name	Description
System.Byte	requestType	bmRequestType type field for the setup packet.
System.Byte	request	bRequest field for the setup packet.
System.UInt16	value	wValue field for the setup packet.
System.UInt16	index	wIndex field for the setup packet.
System.Byte[]	data	Suitably-sized data buffer for either an input or output (depending on the direction bits within a bmRequestType).
System.UInt16	length	wLength field for the setup packet. The data buffer should be at least this size.
System.UInt32	timeout	The time (in milliseconds) that this function should wait for, before giving up due to no response being received (for an unlimited timeout, 0 value should be used).

Returns

Type	Description
System.Int32	Transferred number of the transferred bytes.

Exceptions

Type	Condition
System.NotSupportedException	The required feature is not supported.
System.InvalidOperationException	Throws an exception if the device is disconnected or not opened for an operation.
TimeoutException	Throws an exception if the transfer is timed out.
