** There is a common issue with the Dynamixel XL430-W250 motors where the motors become undiscoverable after their upgrading their firmware from Mac and Windows Dynamixel Wizard2 applications. When this occurs, it is required to do a firmware recovery (Select `DYNAMIXEL Firmware Recovery` and follow the prompts). There are two known workarounds to conduct this firmware reset:
1) Install the Dynamixel Wizard on a linux machine and complete the firmware reset
2) Use the Dynamixel U2D2 in order to perform the reset. This U2D2 can be purchased [here](https://www.robotis.us/u2d2/).
