libusb_strerror with Mustang-V100-MX8 and OpenVino 2020.3

I am using Mustang-V100-MX8-R11 on my Ubuntu 18.04 computer with OpenVino 2020.3.

Linux kernal: 4.15.0-109-generic

I have installed the driver successfully by following https://docs.openvinotoolkit.org/latest/_docs_install_guides_installing_openvino_linux_ivad_vpu.html

I want to verify if it works by following the instructions below-

After configuration is done, you are ready to run the verification scripts with the HDDL Plugin for your Intel® Vision Accelerator Design with Intel® Movidius™ VPUs:

  1. Go to the Inference Engine demo directory:
    cd /opt/intel/openvino/deployment_tools/demo
  2. Run the Image Classification verification script. If you have access to the Internet through the proxy server only, please make sure that it is configured in your OS environment.
    ./demo_squeezenet_download_convert_run.sh -d HDDL
  3. Run the Inference Pipeline verification script:
    ./demo_security_barrier_camera.sh -d HDDL
     
    It shows the following error:
     

    Run Inference Engine classification sample

    Run ./classification_sample_async -d HDDL -i /opt/intel/openvino/deployment_tools/demo/car.png -m /home/aluo/openvino_models/ir/public/squeezenet1.1/FP16/squeezenet1.1.xml

    Error on or near line 217; exiting with status 1

    Could you let me know how to fix it?

Greetings,


Did you tried to run those with "sudo"?



Sincerely,
