Hello,
I'm trying to use the Neural Compute Stick 2 with OpenVINO (2019_R1.1) on Ubuntu 16.04.6 LTS.
I get the error when I run: ./demo_squeezenet_download_convert_run.sh -d MYRIAD
[ INFO ] Loading model to the plugin
E: [ncAPI] [ 723224] ncDeviceOpen:800 Failed connection to device (1.1-ma2480) with error 5
[ ERROR ] Can not init USB device: NC_DEVICE_NOT_FOUND
Error on or near line 241; exiting with status 1
Without "-d MYRIAD" parameter it works fine.
NCS is visible in lsusb (as ID 03e7:2485):
Bus 001 Device 002: ID 03e7:2485
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Below you can find the contents of the /etc/udev/rules.d/97-myriad-usbboot.rules file.
SUBSYSTEM=="usb", ATTRS{idProduct}=="2150", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0660", ENV{ID_MM_DEVICE_IGNORE}="1"
SUBSYSTEM=="usb", ATTRS{idProduct}=="2485", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0660", ENV{ID_MM_DEVICE_IGNORE}="1"
SUBSYSTEM=="usb", ATTRS{idProduct}=="f63b", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0660", ENV{ID_MM_DEVICE_IGNORE}="1"
I run all scripts/commands as a root user.
Maybe someone has any idea how this problem can be solved?
Regards,
Perez

Hi John,
When you see the "NC_DEVICE_NOT_FOUND" message, is the device still listed with lsusb? By any chance are you running Ubuntu as a virtual machine?
Try running the demo with the Neural Compute Stick on a different USB port or powered USB hub.
Regards,
Jesus
