Serial Connection to Hokuyo from Master

Hi,

I am currently getting the error: /dev/ttyACM0 @ 115200 could not open serial device.

Initially, after encountering this problem, I was able to resolve it by adding myself to the dialout list as suggested: https://answers.ros.org/question/286646/error-connecting-to-hokuyo-could-not-open-serial-hokuyo/ I was able to view the data from the Hokuyo after doing this.

I am now trying to access the Hokuyo from a different machine. On the drone (where the Hokuyo is connected), I changed ROS_MASTER_URI and ROS_IP to match the PC. On the PC, I then ran:

$ roscore , $ ssh drone-user@drone-IP

I am able to run '$ rostopic list' correctly. However, after typing '$ rosrun urg_node urg_node', I receive the error mentioned above.

Any help is greatly appreciated.

Thanks,

Justin
