I am using ubuntu 10.04 and ROS electric. I followed the tutorial on
          http://www.ros.org/wiki/sicktoolbox_wrapper/Tutorials/UsingTheSicklms

 When I set the baud rate to be 38400: rosparam set sicklms/baud 38400.The laser works well,but there is a waring: 
&lt;pre&gt;
                A scan was probably missed.
&lt;/pre&gt;
However,when I set the baud rate to be 500000,the laser can't work ,of course ,the baud of laser is 500k.The error is as follow:
&lt;pre&gt;

&lt;/pre&gt;

Is someone using the sicklms200 with the baud rate of 500k well? Maybe you can give me some advices!
