Throw proper error message when udev rules are not set on host. #2
Description
We should also improve the host app and throw a proper error message when the udev rules are not installed (the backend libusb API returns a "permission denied" error in this case).
And in this case potentially offer the user an option to auto-install the rules by running the above script (the user would need to input sudo password).
The udev rules installation could be simplified to not necessarily depend on OpenVINO.
Looks like this works:
Run this command:
echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="03e7", MODE="0666"' | sudo tee /etc/udev/rules.d/80-movidius.rules
Reset or reconnect(USB) the DepthAI device.
