How do I use a USB-hokuyo-laserscanner in ros-kinetic? hokuyo_node seems to be working and pretty well documented (since I'm a beginner using ros, that's important for me, too), but it isn't supported for kinetic. urg_node, since it's the newer driver, should also do the job, but I've got no idea on how to use the USB and not an ethernet interface. Is it even possible? Any suggestions and help setting up (in a ros-beginner-friendly way) would be great. Thanks in advance.

I just got the answer myself.

First I cloned hokuyo_node (git) into ~/catkin_ws/src. Afterwards I called catkin_make which resulted in telling me, that the driver_common package (git) is missing. Cloning this one, too, and I could run catkin_make successfully.
After sourcing ~/catkin_ws/devel/setup.bash again, I was able to call rosrun hokuyo_node hokuyo_node.

From the wiki: The hokuyo_node package is depreciated. The urg_node package should be used for new projects.

Ethernet is only used if the ip_address parameter is set. The package defaults to the serial_port /dev/ttyACM0.

When calling rosrun urg_node urg_noderos is telling me [ERROR] [1483452523.221964309]: Unknown error connecting to Hokuyo. What am I doing wrong?
Edit: Somehow it works now. Thanks again :)

After restarting my system today, it won't work again... Last thing I did yesterday was restarting the system to check whether it works after restart and it did... Why is my sensor not connected today? :(
Btw: Same error as in the post above...

I found out, I first have to run hokuyo_node. After that some bit (I don't know yet...) is set and therefore I'm able running the urg_node... Any ideas anyone?
