I haven't used ROS for about a month to two months, and before this, I've managed to get hokuyo working fine. But just yesterday, I tried to use it again but failed. I run roscore, then in a new terminal, run rosrun hokuyo_node hokuyo_node, but I'm faced with an error:

[ERROR] [1389842311.466153862]: Exception thrown while opening Hokuyo.
buffer filled without end of line being found (in hokuyo::laser::laserReadline) You may find further details at <a href=""></a>

I've seen the troubleshooting page but my error isn't there. I've also tried to uninstall the package using sudo apt-get remove ros-groovy-laser-drivers and reinstalling it with sudo apt-get install ros-groovy-laser-drivers but that didn't help at all.

Would anyone know what happened? I'm just really puzzled because it worked perfectly before.

Have you check your port? In default, hokuyo run on /dev/ttyACM0, do you check whether that port is used by some other device?

Let me know if this helps.

Thanks it helped! My /dev/ttyACM0 was arduino.
