Re : GPIB-USB B trouble after Labview crash

[snormand]

Hi,

I have some trouble with the GPIB-USB NI interface. It works perfectly until my Labview program crashes (which is not the first time and certainly not the last). I need to kill by Windows the labview task.

Then I could not manage to detect again  the GPIB-USB (none of the two leds on the interace works), of course MAX doesn't see the interface, even after reboot.

Any idea how to manage to un-crash the system ?

Thanks

Regards

Hello,

Have you tried to reinstall or repair the drivers?

If you try to plug your device on another USB port, the behavior is the same?

Thanks for your help,

Yes I re-install (x4) driver and NI Labview, MAX, ....

If I change the USB port, the behavior is the same

It seems to be be very sensitive to accidental unplug of the GPIB-USB interface from the computer.

It seems also be sensitive to LAbview crash. In fact after LAbview crash, it doesn't manage to reset the vi so I have to kill the windows task, then the driver doesn't seem to work correctly and I have to re-install every thing (NI488, MAx...) which is very ennoying.

Have you any idea on the VI reset conducts by Labview ?

Hello Stephane,

I got no Idea on the origin of that strange behavior.

Is there a message returning when LabVIEW crashes or something like that?

Regards.
