ClamArm using Dynamixel Motors: No Motors Found

edit

For those of you who are brave enough to try to help me solve this problem, I will grant you 3 wishes. Here we go.

I'm using an arm called the ClamArm

Seen here

http://www.roadnarrows-store.com/clam-arm-servo-kit.html

I just got done building the arm. All motors are powered up. I plugged in both Dynamixel2USB cables from the arm into my computer's USB ports and I run the lowlevel launch file to connect to the arm. (7 motors on the arm total, 3 motors to 1 USB, 4 motors to the other).

Seen here (lowlevel.launch)

<!-- -*- mode: XML -*- -->
<launch>

  <!-- debug capability -->
  <arg name="debug" default="false" />
  <arg unless="$(arg debug)" name="launch_prefix" value="" />
  <arg if="$(arg debug)" name="launch_prefix" value="gdb --ex run --args" />

  <!-- chmod the usb ports -->
  <node name="change_usb_port_permissions" pkg="clam_bringup" type="change_usb_port_permissions.sh" />

  <!-- Startup the arm controller, dynamixel manager, hardware interface, etc -->
  <include file="$(find clam_controller)/launch/clam_controller.launch">
    <arg name="debug" value="$(arg debug)" />
  </include>

  <!-- Send robot XML description to param server -->
  <param name="robot_description" command="cat $(find clam_description)/urdf/clam.urdf" />

  <!-- Publish the robot state -->
  <node name="robot_state_publisher" pkg="robot_state_publisher" type="robot_state_publisher" />

</launch>

I get this error. Apparently, no motors are found!

No Motors found on port_rs485. I look at the launch file and see that it has an embedded launch file called clam_controller.launch that is actually responsible for connecting to the motors.
