setting sensor port permissions
I'm working with different sensors that all require I run things like:
$ sudo chmod a+rw /dev/ttyACM0
$ sudo chmod a+rw /dev/ttyUSB0
to set the port permissions before ROS can see the sensor data. I would like to set these permanently (or somehow in a config or launch file) so I don't need to manually process this step with each attempt to run my app.
Please advise.
