open manipulator x unable to connect to port error

[gandrade2]

I am getting this error and am unsure what to do. ROS was installed correctly, and I am able to manipulate the arm using dynamixel_wizard2

Hi @gandrade2

If you are using U2D2 as USB-DYNAMIXEL interface, make sure to use the command below without any options

$ roslaunch open_manipulator_controller open_manipulator_controller.launch

If you are using OpenCR as an interface, please upload the usb_dxl Arduino sketch to the OpenCR. https://emanual.robotis.com/docs/en/platform/openmanipulator_x/quick_start_guide/#communication-interface

Click on the Option2 box to unfold the content.

Thanks!

@ROBOTIS-Will I am having the same issue and i am using U2D2 board for the control with the above-mentioned command and still it shows the same error. I have also tried changing the USB connector cable but no luck.
