To Reproduce
The following Dockerfile builds successfully, it starts successfully, it mentions the cannot poll() error when I power down the Velodyne, it successfully creates the topic /velodyne_pointclouds. However it does not publish any messages on this topic.
It worked for me with ROS2, I can visualize the /velodyne_points topic through rviz2. I installed from source using colcon from the humble-devel branch.
Please complete the following information:
ros-$ROS_DISTRO-velodyne
sudo dpkg -s ros-$ROS_VERSION-velodyne
