docker run -t -i --privileged -v /dev/bus/usb:/dev/bus/usb kwierman/movidius bash

making run cd cpp; ./hello_ncs_cpp; cd .. Error - Could not open NCS device. mvncStatus value: -2

I've edited the /workspace/ncsdk/api/src/usb_boot.c
Device works from host

Ideas ?

Hey @think-free ,

Sorry for the late response.

I'm the process of recreating the installation steps on a fresh box. I think the one thing I left out by accident was copying the $SDK_DIR/udev/97-usbboot.rules file on the host machine to /etc/udev/rules.d/ and then issuing the commands:

sudo udevadm control --reload-rules
sudo udevadm trigger

If you follow those steps, can you get it work?

Cheers, Kevin

Hi,

I have the same problem as @think-free. I've added the two commands, but docker b to return an error code 2 on sudo udevadm control --reload-rules during the build process. I can manually execute the 2 commands after i'm inside the container, but it doesn't seem to solve the problem
