Hello DongzhiZ,
The computer vision forum for OpenVINO is a more appropriate place for discussion on this topic, I will move this thread there. That being said, I'm concerned about support through OS virtualization software... that may or may not be in the scope of a software supported configuration.

Dear Zhu, Dongzhi,
This Virtual Box USB OpenVino Post may help you. It's not VMWare but the symptom may be the same, which is:
It seems NCS2 USB device ID changes when script starts loading model to MYRIAD.
I was able to resolve it by adding a new USB device filter with VID= 03e7 and PID=f63b in addition to VID= 03e7 and PID=2485 in Virtualbox USB settings.
Hope this solves your problem
Hope it helps,
Thanks,
Shubha

Dear Shubha:
I solved my problem by changing USB controller from 2.0 to 3.0 for all my usb filters in my Virtual machine settings .
Thanks a lot for your suggestion!

Hi Georg,
Could you provide the content of the /etc/udev/rules.d/*myriad-usbboot.rules? Also, it looks like you built OpenVINO from source, could you try using the pre-built package?
Please follow these instructions and download the following OpenVINO toolkit for Raspbian OS package.
Regards,
Jesus

I get the same error with INCS2 on Windows 10 without any virtual boxes. To tell the truth, it works properly from time to time. But in some condition it happens and then nothing helps, including driver re-installation, system reboot, NOTHING. And after some valuable amount of time it works again!
Windows 10
OpenVINO 2020.1 (and OpenVINO2019.3 as well)
INCS2
When INCS2 is recognized by system as Movidius MyriadX among Universal Serial Bus devices output of object_detection_demo_ssd_async.exe looks like this:
InferenceEngine: 00007FF8D48CB740
[ INFO ] Parsing input parameters

While loading model to the device Windows notification appears that said:
The last USB device you connected to this computer malfunctioned, and Windows does not recogize it.
Recommendation: Try reconnecting the device. If Windows still does not recognize it, your device may not be working properly.
After that device is shown in Device Manager as WinUsb Device.

Hi, I would need your help, on the same NC_ERROR issue I am facing, when using OpenVINO DL Workbench. I strictly followed the docker install procedure (https://docs.openvinotoolkit.org/latest/_docs_Workbench_DG_Install_from_Docker_Hub.html). Then, from the UI, after having imported the model and the data and selected the Myriad environment, the inference stops at 23% with the following error messge: "Can not init Myriad device: NC_ERROR". But it works using the CPU environment.
Any Idea?
Thanks in advance.

hi all,
I have the same problem when running the samples on Ubuntu 18.04 (in both VM and non-VM environment).
I worked to run the sample on CPU and GPU, but not with MYRIAD.
I managed to set the USB rules as:
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"
but the same error occurs: "Can not init Myriad device: NC_ERROR".
The solution was to set my_user's primary group to the users group.
I use the following command: newgrp users.
Hope will work four you too.

Hi All,
I have a similar issue with NCS-2 Connectivity, details:
Os- windows 10
model- ResNet-50
I was able to optimize it and got results when running through CPU and NCS-2.
But when NCS-2 is left connected to the system for while without inferencing and try to inference after few minutes it disconnects and throws the error as
"E: [ncAPI] [ 0] [] ncDeviceOpen:859 Device doesn't appear after boot"
And it takes a few minutes to reconnect and give the results.
So, Please suggest me some solution.

HI IIeni, I am running openvino dl workbench UI through a docker container. I tested with the docker run option "--user openvino:users" but I get an error when starting the container ( could not access private key file "/etc/ssl/private/ssl-cert-snakeoil.key": Permission denied ). It seems that setting primary group to users does not give enough access rights.
