The error may be obvious but finding this file and how to install it is not unfortunately. It seems I have to install it from the National Instruments site but Debian Linux doesn't seem to be supported... and I doubt whether just copying this file will be sufficient to make PyVisa work. I wonder whether there might be another way to communicate via USB with a Keithley programmable power supply using Python. best regards, Jean -- http://mail.python.org/mailman/listinfo/python-list
