docker on raspberry pi 3 (resin.io) - Cannot find device

[idata]

Hi

I am trying to use movidius sdk and usb on an resin.io (docker) rpi3 container. I used the latest version of ncsdk2 on a resin/rpi-raspbian:stretch image which attempts to run hello_ncs.py. Both failed for the same reason: "failed to find device"

Here is the Dockerfile:

FROM resin/raspberrypi3-debian:stretch

RUN apt-get update && apt-get install -yq \

install ncsdk2

RUN cd ncsdk && make install

Run post ncsdk install pip installs

RUN pip3 install imutils picamera opencv-python opencv-contrib-python

WORKDIR /ncsdk/examples/apps/hello_ncs_py

CMD ["python3", "hello_ncs.py"]

and this is what I am getting following a successful built of the container image.

The container cannot find the movidius usb but running lsusb on the host gave me this

root@2d6ae06:~# lsusb

Am I missing something on the container or host setup? I am suspecting that the custom udev rules at the end of the ncsdk install are failing.

Thanks
