    Once stopped, cannot find the camera again.

    nissen
      Camera ModelSR300
      HardwareJetson TX2 with Orbitty Carrier
      Operating System & VersionUbuntu 16.04
      Kernel Version (Linux Only)4.4.15-tegra on Jetson TX2

      Problematic Szenario

      The camera is connected to the Jetson over a USB 3.0 Hub and a USB 3.0 extension cable with booster. Once the camera is started with "roslaunch realsense_camera sr300_nodelet_rgbd.launch" everything works fine. Then I stop the camera with ctrl + C. When I then start the camera again with the launch file, it does not find the camera and lsusb does not show the camera.

      The error is:

      [ERROR] [1497343628.338504027]: /camera/driver - No cameras detected!

       

      Working Szenario

      1. The camera is connected to the Jetson only over the USB 3.0 Hub. I can launch the camera with the launch file, stop it with ctrl + C and restart the camera. Everything works fine.

      2. The camera is connected to the Jetson (but with developer kit not orbitty carrier) over the same USB 3.0 Hub and USB 3.0 extension cable with booster. Everything works fine.

       

      Does someone has an idea what to test or a solution? Thanks for your support!
