VI is unresponsive when the computer is connected with the data acquisition card.

Hi everyone:

         VI is unresponsive when the computer is connected with the data acquisition card. But it can run normally unconnected with that. What should I deal with?

When it is NOT connected, it may be simulating, and offering fake data, so all looks fine. When it is connected, it may be timed out - waiting on an input - i.e. it has an error. Please post your VI and tell us what card you are using.
