Hi,
After the upgrade, we have an issue with the USB 3 port, since in the past we connected multiple cameras through the hub, and worked with them, but now, if we start recording with a gstreamer pipeline, like this:

gst-launch-1.0 -ev v4l2src device=“/dev/video$i” ! ‘video/x-raw,format=YV12,width=1280,height=720,framerate=25/1’ ! x264enc speed-preset=ultrafast qp-max=0 ! h264parse ! avimux ! filesink location=“cam_$i”.av

and stop the pipeline, all works fine, but the second time you start recording, it won’t pull any information from the camera, unless you re-plug the camera, if you don’t after the second try, the whole system colapses, and the only way is to restart the board, hope anyone can help.

You can probably gather information most easily if you have a serial console. This would show errors as they occur, and for the most part, even when the system is dying. See:

Alternately, after reboot, you may see something in “/var/log/”, e.g., “kern.log” or “syslog” (or “kern.log.1” or “syslog.1”). If X11 was involved you may see hints in “Xorg.0.log” or “Xorg.0.log.old”. Perhaps a terminal logged in via ssh would catch the tail of a message.
