Hi @dangirahul215


Is your host machine running Windows? Here is a thread discussing this issue and here is the workaround that helped others:


"Set up the Movidius driver for Windows with the following instructions and try again from virtualbox




If you can't find "PluginMyriad.html", please go to c:\intel\computer_vision_sdk_xxxx\deployment_tools\documentation.


Open "index.html" with google chrome or internet explorer.


Look for "MYRIAD" and click.


You should set up the Movidius driver manually in Windows."


Also, all NCS2 + OpenVINO questions are posted here in the Computer Vision forums (for future reference :) )


I hope this was helpful!


Best Regards,
