I'd like to run a usb camera in Balena OS, but that means I need docker without volume mounts. What is the blocker for enabling this feature?

this works:

docker run --rm \
     --privileged \
     -v /dev/bus/usb:/dev/bus/usb \
     --device-cgroup-rule='c 189:* rmw' \
     -e DISPLAY=$DISPLAY \
     -v /tmp/.X11-unix:/tmp/.X11-unix \
     luxonis/depthai-library:latest \
     python3 /depthai-python/examples/ColorCamera/rgb_preview.py

this doesn't:

docker run --rm \
  --privileged \
  --device=/dev/bus/usb \
  --device=/dev/usb \
  --device=/dev/dri \
  --device-cgroup-rule="c 81:* rmw" \
  --device-cgroup-rule="c 189:* rmw" \
  -e DISPLAY=$DISPLAY \
  -v /tmp/.X11-unix:/tmp/.X11-unix \
  luxonis/depthai-library:latest \
  python3 /depthai-python/examples/ColorCamera/rgb_preview.py

Traceback (most recent call last): File "/depthai-python/examples/ColorCamera/rgb_preview.py", line 24, in <module> with dai.Device(pipeline) as device: RuntimeError: Failed to find device after booting, error message: X_LINK_DEVICE_NOT_FOUND

is there an example of measuring the distance between two 3D points, something like IntelRealSense/librealsenseblob/master/examples/measure/rs-measure.cpp#L286-#L295 or
