Hi, we have noticed across many of our D435 devices that the USB connection is not reliable. In other words, our computer isn't able to consistently recognize the camera.
This is easily reproducible even with the most basic configuration -- using the out-of-box D435 cable and running the Intel RealSense Viewer app. In this setup, the Viewer will often not recognize that the camera is present. We also notice this issue when we're using the D435 with the Librealsense SDK, where we aren't able to communicate with camera. The fix has typically been to unplug & replug the camera, and then retry the connection (whether that's restarting the Viewer app, or re-running our SDK code). However, this solution is not scalable for us, since we're trying to use the camera in production scenarios where we can't easily unplug & replug the camera.
This seems like a firmware issue with the camera? What are the guarantees or expectations that the camera will be recognized each time? Do you have suggestions for more reliable ways to re-establish a connection without necessarily unplugging and replugging?
Additionally, if we want to use another USB cable, what are the precise specifications for the cable that we should follow? Any constraints we should be aware of (i.e. max recommended length of the USB cable, etc)?
Thank you for your guidance.
