“Failed to open USBDynamixel” troubleshooting

Recently I met a problem while opening Dynamixel motors with USBDynamixel like the below picture.

My environment is Ubuntu 12.04 and patched with RT-preempted to make my PC real-time.

The solution is very simple, just use “sudo“. ¬†You can see the result in the below picture.
