Is anybody familiar with rosserial for arduino? I tried adding the rosserial_python to the lamunch file for my robot and got the following error message

[ERROR] [WallTime: 1405182789.065153] Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino

I checked and I know my software version is not mismatched, So what is the problem and the solution? I am currently using ubuntu 12.04 with Hydro Medusa. I've also included the relevant portion of launch file

  <node pkg="rosserial_python" type="serial_node.py" name="rosserial" output="screen">
<param name="~port" value="/dev/ttyACM0" />
<param name="~baud" value="57600" />

</node>

<param> tags that are nested inside a <node> tag automatically imply that the parameters will be set in the node's namespace.

Try this launch file instead:

<node pkg="rosserial_python" type="serial_node.py" name="rosserial" output="screen">
  <param name="port" value="/dev/ttyACM0" />
  <param name="baud" value="57600" />
</node>
