Issue Details

  • I get an undefined Error -2147220969 when running a LabVIEW code to acquire images using NI-IMAQdx and an USB 2.0 camera.
  • My camera works in NI MAX but in LabVIEW I get an unknown Error -2147220969. 

Solution

This error could be caused by incompatibility with the USB cable, because of the following reasons:
1. The USB cable is too long.
2. Use of USB extenders. 
3. Use of other accessories like hubs. 

Note: This affects your application because the power signal dissipates thorugh the cable, resulting in the error described above.
