I was trying CV SDK in version 2018.2.319 on Ubuntu16.04, running the object_detection_demo_ssd_async sample with myriadPlugin, but I got problem shown as below:
End with [ERROR] Unknown device
What could be the problem?
********************************************************************************************************************
sudo ./object_detection_demo_ssd_async -i /dev/video0 -m MobileNetSSD_deploy.xml -d MYRIAD
InferenceEngine:

Hi Monica,
Have you loaded the usb rules for the MYRIAD device. They can be found in /opt/intel/computer_vision_sdk/deployment_tools/documentation, click OpenVINO_Deployment_Tools_documentation.html, click Inference Engine Developers Guide, and then scroll down and click MYRIAD at the bottom of the page are instructions on how to load the USB rules for MYRIAD. Let me know if this helps as I've successfully ran the sample on MYRIAD but i'm also on R3 which is now the latest OpenVINO release.
Kind Regards,
Monique Jones

Hi Monique,
I'm sure I have loaded the 97-usbboot.rules in /etc/udev/rules.d.
I've successfully run the hello_ncs_cpp in NCSDK2 :
/workspace/ncsdk2/examples/apps/hello_ncs_cpp/cpp$ ./hello_ncs_cpp
Hello NCS! Device opened normally.
Goodbye NCS! Device Closed normally.
NCS device working.
In fact, I succeeded in running the samples before I reinstalled the openvino R2.
I have tested in so some ways:
1) reinstall R2 with root privilege (fail)
2)run ncsdk2 (success )
3) lsusb (success)(with 2 movidius sticks)

I am so confused about the problem. Looking forward to your reply.
