I'm using um7 sensor plugged on a Robotino 2 through a USB connection, which becomes avaible on the robot OS as the /dev/ttyUSB0 device.

ROS run from my laptop using the robotino_node whith the following command:

roslaunch robotino_node robotino_node.launch hostname:=robotino_ip

And also from my laptop I run:

rosrun um7 um7_driver _port:=/dev/ttyUSB0

Which returns:

[ WARN] [1509236905.663885439]: um7_driver was unable to connect to port /dev/ttyUSB0.
[ WARN] [1509236905.663999386]: Could not connect to serial device /dev/ttyUSB0. Trying again every 1 second.
[ WARN] [1509236906.664321331]: um7_driver was unable to connect to port /dev/ttyUSB0.

As I can understand, the driver is trying to use the device /dev/ttyUSB0 right from my own laptop instead of the Robotino one.

Is there anyway to force the drive to use the Robotino device?
