hi,

when i start the hokuyo_node, there is a ERROR: Exception thrown while opening Hokuyo. Device /dev/ttyACM0 ist already locked. Try "lsof grep /dev/ttyACM0" to find other processes that currently have the port open...

i already checked that the Hokuyo cam is on Port /dev/ttyACM0.

How can I fix it?

Thank you!
