Problems with launching the Schunk LWA 4P

edit

Hi together,

i'm using Ubuntu 14.04 with 3.19.0-80-generic kernel, ROS-Indigo and the PEAK USB-CAN interface. I'm trying to run the "robot.launch" file of this package https://github.com/ipa320/schunk_robo... for the Schunk LWA 4P installed on the SCOUT active, but it doesn't finish and i get this log-messages. I'm directly connected with the Schunk LWA 4P:
