pan_tilt_port: No motors found ERROR

Hi, I am testing a created package on ROS by following the tutorial... http://wiki.ros.org/dynamixel_controllers/Tutorials/ConnectingToDynamixelBus

while running the command: "roslaunch mydynamixeltutorial controller_manager.launch" it give the error as "No motors found" even though the motor XL430W250 is connected with default baud rate of 57600 through /dev/ttyUSB0

Please help to resolve this! Thanks!

Here are some things to try/consider:

Did you set the right permissions for the USB device? Try sudo chmod a+rw /dev/ttyUSB0.
Is the motor sufficiently powered? Make sure your wiring is correct. If you're just powering the motor through the USB, it probably won't work.
Are you aware that this package hasn't been maintained for years and it is recommended to use the official repo, Dynamixel Workbench?
