Problem with nmea_navsat_driver

edit

I try to connect MBED C027 with gps to ROS Kinect. I install package and I want to to try run ROS as in example from http://wiki.ros.org/nmea_navsat_driver

$ rosrun nmea_navsat_driver nmea_serial_driver _port:=/dev/ttyUSB0

but on my Ubuntu 16.04 LTS there is no dev/ttyUSB0 but dev/ttyACM0 so I change above formula to :

$ rosrun nmea_navsat_driver nmea_serial_driver _port:=/dev/ttyACM0

and I have message on my terminal:

[WARN] [1488637721.102995]: Received a sentence with an invalid checksum.

Traceback (most recent call last):
File "/opt/ros/kinetic/lib/nmea_navsat_driver/nmea_serial_driver", line 52, in <module> data = GPS.readline().strip() File "/usr/lib/python2.7/dist-packages/serial/serialposix.py", line 511, in read raise SerialException('read failed: %s' % (e,)) serial.serialutil.SerialException: read failed: (4, 'Interrupted system call')

I consider that this path dev/ttyACM0 might cause problem to connect but I can't find a solution Anyone have any advice?

Thanks :)
