Using Asus Xtion with electric failing depth stream

edit

Hey All,

I am trying to get my Asus Xtion working with electric using the openni_launch but I keep getting the following error;

terminate called after throwing an instance of 'openni_wrapper::OpenNIException'
what():  virtual void openni_wrapper::OpenNIDevice::startDepthStream() @ /tmp/buildd/ros-electric-openni-  kinect-0.3.2/debian/ros-electric-openni-kinect/opt/ros/electric/stacks/openni_kinect/openni_camera/src/openni_device.cpp @ 257 : starting depth stream failed. Reason: Xiron OS got an event timeout!

I am starting the kinect using the standard procedure from the wiki as follows;

roslaunch openni_launch openni.launch

Then I start rviz using rosrun rviz rviz, and immediately when I set the Fixed frame to /camera/depth_optical_frame and the topic to /camera/depth/points, I get the error above. I have tried changing the usb ports and even doing a sudo chmod 777 /dev/bus/usb but no change so far.

Any suggestions are welcome.

P.S. The MS Kinect works without a problem though.
