Error to run swissranger camera (sr4000) even after udev rules edition

edit

Hi,

I followd "Download and install swissranger_camera tutorial" (I use ROS kinetic on Ubuntu 16.04 and installed the Ubuntu on virtuall machine).I edited the udev rules, and I also run sudo chmod -R a+rwx /dev/bus/usb.

When I run

rosrun swissranger_camera swissranger_camera

I got this error

[ERROR] [1477869827.785201373]: Exception thrown while connecting to the camera: [SR::open]: Failed to open device!

How I can solve this issue?

Thanks,

Abbas
