Hello,
The device will reboot when the model is loaded and will reconnect as "VSC Loopback Device". The OpenVINO will run inference while the device is in this mode, however, there is something installed on the machine that is conflicting with the device.

Hello,
Are there any other SDK environments that may be set up or other versions of Python installed? In addition, could you try the new OpenVINO release R3.1, please?
Thank you.

Hi, blechatellier,
I hope you are doing well. I was checking your case and I noticed we do not have a reply from you yet.

Still running into the same issue with the latest version of openvino. As soon as I run the demo app I get "E: [ncAPI] [ 393744] [] ncDeviceOpen:859 Device doesn't appear after boot".
Then the device disappears from the list when using "system_profiler SPUSBDataType". I have to remove the device and replug.
That's very frustrating, any resolution in mind?

Hello,
We have tested multiple Mac systems with OpenVINO 2019 R3.1 and we have not been able to replicate the same behavior you are seeing. We understand your frustration and we are doing our best on finding a resolution to your issue. I have confirmed you have all the required software versions installed, which leads us to believe there may be other software installed on the system that may be conflicting with the OpenVINO toolkit and the Intel® Neural Compute Stick 2.
As a last resort, you can try testing on a fresh install of Mac OS X. Our systems had a fresh install of macOS which worked for us, but we cannot assure you this will fix your issue.
Thank you for your comprehension.

I've already tested on multiple computers so it's unlikely that another software is conflicting, do you have any debug tool that could help understand why the USB device gets ejected after running the sample app?

Hi blechatellier,
Thank you for your patience while we looked further into your request. I tested the Intel Neural Compute Stick 2 on a fresh MacOS X Mojave install and did not have any issues running the demos.
One thing I did notice is that your system_profiler SPUSBDataType output shows the Intel NCS 2 is connected to a USB 2.0 hub. The Intel NCS 2 needs to be connected to a USB 3.0 port, could you try connecting the device directly and confirm it's detected under USB 3.0?
Also, please try to match the following software versions.
- CMake 3.15.5
- Python 3.6.5
- Apple Xcode Command Line Tools 11.2
Regards,
Jesus
