Hello all,

We are facing some issues when using D435 cameras on Linux systems. Please find next our platform, software versions, etc. scenario.

Camera: D435

SDK: librealsense 2.0

OS: Linux

Distribution: Ubuntu

Release: 16.04.6 LTS

Kernel: 4.4.0-166-generic

Installation steps: https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md 

Development framework: Python wrapper. (pyrealsense2 2.28.0.1093)

dmesg error messages:

These errors arise when running the code example from here.

Maybe we have missed some installation steps. We will appreciate any help in this concern.

Thank very much in advance.

    A number of other users have experienced this error.  My research indicates that the RealSense team members took a good look at it over these various cases but a single definitive solution did not emerge.  The two main recommendations were to try a kernel upgrade, or use a mains-powered USB hub to help ensure that the camera is not being forcibly disconnected.

    I note that you are using Kernel 4.4, which is the absolute minimum kernel for RealSense SDK 2.0.  Would it be possible to update your project to a more recent kernel, please?
