Kinect could be used without calibration

UPDATE: As you can see the openni_camera package has a pre-calibrated param file for Kinect, you can calibrate it again but not doing so won't have problem in launching the device.

How did you bring up the device before you can see published /camera/depth/points topic? The openni_camera package is not dramatically changed between Diamondback and Electric. Please post the error message to further investigate the problem.
