[Detector Support]: Intel Myriad VPU [Movidius Neural Compute Stick] v1

[Pirionfr]

Describe the problem you are having

I have an Intel NCS Myriad stick not a NCS2 I'm trying to make it work by following the doc here on my rpi4 but I get this error "RuntimeError: Failed to allocate graph: MYRIAD device is not opened"

in the udev rules I added : SUBSYSTEM=="usb", ATTRS{idProduct}=="2150", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0666", ENV{ID_MM_DEVICE_IGNORE}="1"

someone can help me ?

I'd suggest reading https://github.com/blakeblackshear/frigate/discussions/3797 where some users tested on the NCS

[NateMeyer]

I don't think Intel's OpenVino library currently supports the v1 NCS. I'm unsure when the last supported library version was. They also have removed support for the MYRIAD plugin and NCS2 stick in 2023.x versions.

[NickM-27]

Ah my bad, thanks for the correction. Perhaps we should update the docs to specify myriad device is NCS2 only?
