I'm using a Plugable USB to RS-232 connector to connect the laser, I'll RS directly.

Also just noticed you need to run this command

rosrun sicktoolbox_wrapper sicklms

Did you run:

sudo apt-get install ros-hydro-sicktoolbox-wrapper

Also check if there's anything under:

ls /opt/ros/hydro/lib/sicktoolbox_wrapper/

If you're on a pioneer, please use the connect_delay parameter: http://wiki.ros.org/sicktoolbox_wrapper#Parameters

rosrun sicktoolbox_wrapper sicklms _connect_delay:=30.0

Does your laser have a solid green light, indicating it's ready for use?

Does it work in Windows or any other software? It's possible your cable or adapter is incorrect (RS 232, RS 422, broken wire).
