Hello;
That is a known issue which there is a workaround for it.
You need to uninstall NI-DAQ 6.9.1 and install 6.9.2 from our web site.
Also, you need to:
Copy nicfq32.dll and nipsm.dll into the system32 directory, and copy nihwdb.psm into the Winnt directory.
In MAX, you will see both cards. At this time, however, they will show up as the same socket number, and we are not displaying the controller number, so you'll have to put the cards in one at a time to figure out which card is assigned to which device number.
All the files needed for the fix are attached to this response.
Hope this fixes the problem.
