FLIR 46-70 connectivity error. [closed]

edit

Hello all,

I recently got a Flir 46-70 PTU and I'm having quite a trouble with it. I cloned the repo from here and catkin_make without a problem.

When I try to launch the launch file provided I get the error below:

My launch file is:

<launch>
<arg name="port" default="/dev/ttyUSB0" />

<!-- When you integrate into your platform, use the provided xacro macro to include
   the D46 URDF with your larger platform description, and have your platform's
   joint_state_publisher subscribe to the ptu state. -->
<param name="robot_description" textfile="$(find flir_ptu_description)/urdf/example.urdf" /> 
<node name="robot_state_publisher" pkg="robot_state_publisher" type="state_publisher" />

<node name="ptu_driver" pkg="flir_ptu_driver" type="ptu_node" ns="ptu">
<!-- <param name="port" value="$(arg port)" /> -->
<param name="port" value="/dev/ttyUSB0" />
<remap from="state" to="/joint_states" />
</node>
</launch>

Finally my setup is ROS hydro, with ubuntu 12.04. I realize that there is a question in : http://answers.ros.org/question/20294... but the answers doesn't seem to help me.

Edit 1) I'm starting to suspect a faulty serial to usb converter.
