hi,
well this error means most of the time, that you did not select the apropriate device in the "VISA resource name" Control on the Front Panel. You will be able to select a device that appears in MAX ( Measurement & Automation Explorer).
Is you device recognized in MAX?
If not, is it in the "windows device manager"?
When using VISA, you are able to communicate with the device in MAX, using a VISA Querry, like a test panel. Send a "*IDN?" to you device and see if it answers.
Since you did not provide a link to the driver, i was not able to look into the Driver VIs, but i asume it uses NI VISA VIs.

thx, i have soluted this Question.
Here is a methode in internet to connect computer with GPIB.
Measurement & Automation Explorer 4.x
To use the VISA Passport editor in MAX 4.x, select Tools » NI-VISA » VISA Options... Once the VISA Options screen appears, select Passports in the tree view (My System » General Settings » Passports). Enable the NiVisaTulip.dll by placing a check mark in the box beside it and then click on the Save button. You will need to restart MAX for the setting to take effect. Once MAX is restarted, you will be able to access your third-party GPIB boards and give them VISA aliases under My System » Devices and Interfaces » Miscellaneous VISA Resources.
Wenn i enable the NiVisaTulip.dll, my Labview can not read the VISA resource name. But wenn i again disable the dll. Problem done.

Good to hear you solved it on your own.
Incase you still want to know where this too could be found:
