Timeout Error for Hokuyo Node with URG-04LX-UG01 Sensor
I'm using Ubuntu 12.04 with ROS Hydro, and seeing the same error as: http://answers.ros.org/question/45850/problem-running-hokuyo_node/:
>> rosrun hokuyo_node hokuyo_node _port:=/dev/ttyACM0
[ERROR] [1422560559.586392534]: Exception thrown while opening Hokuyo.
timeout reached (in hokuyo::laser::laserReadline) You may find further details at http://www.ros.org/wiki/hokuyo_node/Troubleshooting
I think I do have the correct permissions on /dev/ttyACM0 since:
>> ls -l /dev/ttyACM*B0
crwxrwxrwx 1 root dialout 166, 0 Jan 29 14:42 /dev/ttyACM0
Solution: Use a different USB cable.

Do you actually need the _ in your parameter name? ie port instead of _port? ref: http://wiki.ros.org/hokuyo_node/Tutorials/UsingTheHokuyoNode the parameters for portname is port

I don't think so. Also, the same error occurs when I run:
rosrun hokuyo_node getID /dev/ttyACM0 [ WARN] [1422638157.691061366]: getID failed: timeout reached (in hokuyo::laser::laserReadline) You may find further details at http://www.ros.org/wiki/hokuyo_node/Troubleshooting
