Hello Everyone, I'm following the tutorial dynamixel_controllers/Tutorials/ConnectingToDynamixelBus and I cannot found my motor XM430

When I ran the roslaunch command I receive this:

[FATAL] [1526461074.024123]: pan_tilt_port: No motors found.
================================================================================REQUIRED process [dynamixel_manager-2] has died!

Yes, I'm using the correct port because I could do the read_write tutorial using the exactly same port /dev/ttyUSB0 But for this tutorial I couldn't.
