kinect issues on different machines

edit

Hi,

I tried running the following launch script, with my kinect, on two different machines, on the first one (desktop) everything works fine, on the second one (laptop) nothing works:

<launch>
  <!-- kinect and frame ids -->
  <include file="$(find openni_camera)/launch/openni_node.launch"/>

  <!-- openni manager -->
  <node pkg="nodelet" type="nodelet" name="openni_manager" output="screen" respawn="true" args="manager"/>

  <!-- throttling -->
  <node pkg="nodelet" type="nodelet" name="pointcloud_throttle" args="load pointcloud_to_laserscan/CloudThrottle openni_manager">
    <param name="max_rate" value="2"/>
    <remap from="cloud_in" to="/camera/depth/points"/>
    <remap from="cloud_out" to="cloud_throttled"/>
  </node>

  <!-- fake laser -->
  <node pkg="nodelet" type="nodelet" name="kinect_laser" args="load pointcloud_to_laserscan/CloudToScan openni_manager">
    <param name="output_frame_id" value="/openni_depth_frame"/>
    <remap from="cloud" to="cloud_throttled"/>
  </node>
</launch>

on the laptop the output looks exaclty the same like on the desktop:

no errors, nothing.

The problem is that on the laptop there is nothing going one on the topics. e.g. listening to /camera/depth/points or /scan on the desktop I can see messages comming in, on the laptop there is nothing, silence.

There is a difference in the dmesg output. On the desktop:
