I have installed NI-DAQMX BAse software on a PC. When I connect my USB-6501, I doesn't see my USB-6501 with the program "Measurement & Automation ". The Windows2000 Hardware Device Manager detect the USB-6501. I am not administrator on that PC.
You have to use the Daqmx Base configuration Utility in Start> National Instruments> Daqmx Base. You can also not use the Daq Assistant which is supported by daqmx not by Base.
