Hokuyo laser getID failed. How to fix it?

edit

Make sure the laser driver is installed correctly and the system can read it. Connect your laser and check if the system can detect it and if it is configured correctly.

$ ls -l /dev/ttyACM0

When the laser is connected, the system can see it using the following command line:

crw-rw-rw- 1 root dialout 166, 0 Jun 15 11:17 /dev/ttyACM0

Once everything is OK, we are going to switch on the laser. Start roscore in one shell and in another shell execute the following command:

$ rosrun hokuyo_node hokuyo_node

If everything is fine, you will see the following output:
