Trouble setting up interface with CB LE4

I’m afraid I’m out of ideas. Unless someone else comes along who has used the same device I think you are going to have to go through NI support.

One thing you could try is the ASIO4ALL driver …

Not a permanent solution, but it might get you up and running for the time being while you figure out what is going on with the native driver for your device.
