Hi, I use ros-kinetic and try to read data from esd can/usb2 connector but get the following error messages. Anyone can kindly help? Thanks!

rosrun socketcan_interface socketcan_dump can0
ERROR: state=1 internal_error=0('OK') asio: system:0
ERROR: state=2 internal_error=0('OK') asio: system:0

Don't worry, this is normal. In the devel version it reads "STATE" instead of "ERROR" (https://github.com/ros-industrial/ros_canopen/pull/372), but I did not push a new release yet.

New release: https://github.com/ros/rosdistro/pull/26274
