MAX can not find "GPIB-USB-B" under" Devices and Interfaces"

[PCASC]

Hi,

I am using Labview 2010 with windows 7 system (64bit).

I am trying to work on some program for Keithley 2700, connected with "GPIB-USB-B" with my computer.

The problem is that MAX can not find "GPIB-USB-B" under" Devices and Interfaces" from time to time, everytime I have to restart my computer to find the device. The driver I used is NI-488.2.2.81.

Is there any advice that I do not need to restart computer agian and agian?>

Thanks

Hi,

If your device is not listed, then I strongly recommend you to check the VISA Passports. To check the VISA Passports, open the NI Measurement & Automation (NI Max) utility and click on Software->NI-VISA, go to the VISA-Options tab, click on Passports and ensure the NI-VISA Passport for GPIB is marked off and the KEVICec Visa Passport for GPIB is marked on.
