Error -1073807343 when calling the open visa function

[PascThom]

Hello,
I already posted my question but I forgot to say that I am using a PCI-GPIB card. So, I post it again :
I have Error -1073807343 when calling the open visa function, I am running a Labview 6i under Linux (kernel 2.4).
I have verified the name of the session (GPIB0::9::INSTR), and I can communicate with my instruments with ibic.
More informations : I use NIVISA 2.5 and nigpib-0.8.2. I have downloaded the lastest drivers of my instruments but it doesn't work better.
Thanks very much for your help.

The error is defined by LV as:
"Error -1073807343 occurred at an unidentified location

Possible reason(s):

VISA: (Hex 0xBFFF0011) Insufficient location information or the device or resource is not present in the system."

It looks as though the name of the session is okay, because it should look like => GPIB0::9::INSTR

Are you using this name to open the VISA session or to initialize the instrument?

Once the session is opened, you should get a name like:
GPIB0::9::INST followed by the session number..

Unfortunately I don't have a true example of the number, but it looks like... GPIB0::9::INST:1 I'm not sure if the column is in front of the 1.

Hope this helps..

JLV

Thank you for your help.
The error occures when I open the Visa session with Labview, with the function "Visa open".
Have a good day !
