Multiple computers have NI USB DAQ errors

[Christiana]

I have five computers that simultaneously lost connection to the NI DAQ USB card connected to them.  On each computer it appears that the DAQ device driver is no longer on the computer and the MAX database is corrupt.  I have fixed two of the five computers by deleting the MAX database files and restarting the computer. Has anyone else had this problem?

Random information....

All of the computers have NI-DAQmx 9 to 9.6. 

Uninstalling and reinstalling the latest version of DAQ does not resolve the problem.

No virusus are detected by the anti virus software.

All the computers are running Windows 7 32bit.

USB GPIB works correctly.

I went to the NI support web site and found this link:

I restarted NI Device Loader and MAX was able to detect the USB DAQ cards.

I do not know why NI Device Loader stopped running on so many computers. I suspect it may be something IT changed on all of the computers for security reasons.

 I would also recommend setting the recovery option in the Device Loader Properties to Restart for each failure mode.
