Hi:

I am encountering the same problems as Henning's post with the error in configuration file as well as "tried to advertise service that is already advertised in this node". As a result, my rviz shows that for the pointcloud2 display the topics are not publishing any messages. Has anyone successfully resolved this issue? Restarting the driver X # of times cannot possibly be the only way... I am running Ubuntu 11.04 with rose electric and my USB ports are 2.0.

Thanks in advance
