High resolution USB3.0 camera support in RB5

Hi there,

I'm trying to stream 13MP resolution from USB3.0 camera connected to RB5 using gstreamer and v4l2-ctl applications. I'm able to stream VGA resolution but if I streaming any higher resolutions (720p, 1080p, 13MP) the camera streaming stops.

Gstreamer pipeline:

Working pipeline:
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=UYVY,width=640,height=480 ! videoconvert ! fpsdisplaysink sync=false -v

Not working pipeline:
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=UYVY,width=1920,height=1080 ! videoconvert ! fpsdisplaysink sync=false -v

v4l2-ctl:

Working:
v4l2-ctl --device=/dev/video0 --set-fmt-video=width=640,height=480,pixelformat=UYVY --stream-mmap

Not working:
v4l2-ctl --device=/dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=UYVY --stream-mmap

Is there any kind of memory limitation/USB limitation in the RB5 kit? If yes, could you please share how to resolve this to stream the 13MP resolution?

I tried connecting the camera in USB2.0 mode (connected camera to RB5 kit using an USB 2.0 hub), and able to stream the 13MP resolution. Is there any limitation in RB5 USB3.0 interface?
