SDC2130 launch ROS connection

Hello everyone

I'm starting to work with the SDC2130, and node ROS Roboteq, and have the launch of the evidence, I compile and execute the launch, but I'm having an error and did not connect the driver, and displays the following message, "Bad Error Connection with serial port / dev / ttyACM0 ".

I'm using the USB connection, the configuration of the port is 115200/1/1 / N. I do not know I'm doing wrong, someone could help me with this? I thank you very much
