Hi all! I have Ubuntu 16.04 LTS and a kinetic ROS on my pc. I am trying to stream a realsense node, but my computer doesn't read anymore the realsense sr300 camera that I am using, and I don't know why! I mean.. I have used it at the end of january and it worked perfectly! After I didn't execute any upgrade or similar, and now when I try to start the node 'roslaunch realsense2camera rscamera.launch', the terminal show me this output:

started roslaunch server http://alessiadele:39303/

I've tried with 'sudo apt-get update', and after a long processing, the camera still not work.

Do you have any suggestions? thank you!
