	offset As Integer, _
	length As Integer, _
	timeout As Integer, _
	<OutAttribute> ByRef transferContext As UsbTransfer _
) As ErrorCode

	int offset, 
	int length, 
	int timeout, 
	[OutAttribute] UsbTransfer^% transferContext
)

offset (Int32): Position in buffer that transferring begins.

length (Int32): Number of bytes, starting from thr offset parameter to transfer.

timeout (Int32): Maximum time to wait for the transfer to complete.

transferContext (UsbTransfer%): On Success, a new transfer context.
