The Kinect does not work well on USB 3.0 Ports. If possible try to attach it to an 2.0 Port. Also have a look at the openni driver console for any error related output.

There is a problem with the transforms I guess. This is a TurtleBot tutorial and you aren't using a TurtleBot. If you change the fixed frame to something else, then everything should work fine. Or, simply run

roslaunch openni_launch openni.launch

This is the launch fine for just kinect. I suggest you use this one.

Topic for PointCloud2 should be /camera/depth/points or /camera/depth_registered/points.

Also I have no problem running kinect from my USB 3.0 port in ubuntu 11.10.
