I don't have the instrument and the test you performed really doesn't help much since the driver uses the low level GPIB functions. Make sure to edit the HP 3561A and HP2561A.read VIs and change the address that is in there to match what your instrument's actually is. It's hard coded for address 11. You also want to make sure that the automatic error handling is turned on. There is none in the driver VIs.
That being said, the driver is old and unsupported. You might want to redo it or use the Instrument I/O Assistant.
