Hi, this is my first time to use ueye camera. My camera is UI324xLe-M. I installed the driver 4.91.0001. All things are good when I tried to launch the camera by camera Manager. So I tried to launch the camera by ROS. After catkin_make the package. I entry the sudo /etc/init.d/ueyeusbdrc start to start the driver first. Then launch the roscore in a new terminal. At last I cd to catkin_ws/src/ueye_cam/launch/ and run roslaunch rgb8.launch in terminal. But error happens:

I don't know why this happens, can anybody help me?

I don't know why you are getting this error. Exit code -6 might be due to Linux System Error code 6, which apparently says "No such device or address". If that's truly the problem, then you should make sure that your camera is properly connected, powered on, and the USB cable is stable, USB hub available, etc.

Otherwise, since I can't replicate your error on my setup, you will have to debug which line of this code (e.g. via gdb) is crashing, in order to dig deeper.

Good luck.

I get the same error message. Camera is a UI-3013XC-C, installed the software suite and started the driver (sudo /etc/init.d/ueyeusbdrc start).

Did you manage to find a solution?
