VISA-Resource-name constant results in flashing disk access

[lenny]

If I connect a VISA-resource-name constant to the VISA-Serial-Configure-Port.VI the Harddisk access lamp flashes. There is a repetetive access to the files: system.in, VISAconf.ini, GPIB.vxd and LPT1.vxd.
(Configuration: Laptop, Windows ME, LabView 6.02, GPIB-PCMCIA installed)
Any suggestions?
Is this behavior by design? How can I stop the disc access?

Hi,

Most of the file access and CPU activity occurs only when a VISA control/constant/indicator is placed on a VI. This causes the VISA driver to load and search the available VISA resources. most of the disk activity is to read the configuration files to detect any reasource installed on the system and if they have VISA aliases. GPIB.INI is also accessed since VISA detects any device connected to the bus. Most likely there are also other internal setup that the driver is doing.

As far as I know, there is no way to disable this.

Hi DiegoF,
thanks for your answer.
I solved the problem by updating the VISA-Driver version 2.5 to 2.6. This stops the file access.

Thank you
