I am surprised that PCI-6221 can be detected in the "device administrator" of my computer, but it can't be detected in the MAX after updating DAQmx to 8.0 from 7.4. I have uninstalled completely DAQmx8.0 and MAX on my computer, and then reinstalled DAQmx7.4 on the computer, but I can't see the PCI-6221 card in the MAX, and it isn't used by calling some DAQmx functions with Labview7.1.
Could you anybody help me to fix this problem? Thanks in advance.
I had similar problems in the past, although with other cards. I fixed it by opening the device properties in the Windows device manager and refreshing the driver (letting Windows to choose the correct one automatically).
