Creates a new transfer queue instance.

public UsbTransferQueue ( UsbEndpointBase endpointBase, int maxOutstandingIO, int bufferSize, int timeout, int isoPacketSize ) : System
endpointBase	UsbEndpointBase	The endpoint to transfer data to/from.
maxOutstandingIO	int	The number of transfers to before waiting for a completion.
bufferSize	int	The size of each data buffer.
timeout	int	The maximum time to wait for each transfer.
