Connecting to Pixy2 cam over USB #1

I am connecting Pixy2cam to ROS. Platform is the Nvidia Jetson Nano. I have pixy2 library with libpixyusb2 built. pixy2_ros built with no errors in my catkin workspace. Error message below when running roslaunch pixy2_ros pixy2.launch. rosrun pixy2_ros pixy2_cam also doesn't work.

Hello,

Can you tell me how to resolve this issue?

Thank you.

@leeyunhome I do not know really. Have you copied the pixy.rules rules? Maybe the first option is to check everything works from the official site and your linux environment. Then I would try again with this ROS node. Hope it helps, regards
