Downloading PDO communication object failed! with schunk_canopen_driver (CAN_ERR_OK)

edit

Hi,

i'm using Ubuntu 14.04 with 4.4.0-148-generic kernel, ROS-Indigo and the PEAK USB-CAN interface. I followed the instructions at http://wiki.ros.org/schunk_canopen_dr... to build from source. So automatic the peak-driver 8.3.0 has been installed. I try to run the Schunk LWA4P or. the Scout active which is equipped with the Schunk, but I am directly connected with the LWA4P.

So when I run the launchfle $ roslaunch schunk_canopen_driver standalone_profile_position.launch I get this output:

$ roslaunch schunk_canopen_driver standalone_profile_position.launch
