[Error 7] Toolkit Error: USB Failure. Code: Error opening device

I ran the example of mobilenet V1 as the following instructions:
https://github.com/movidius/ncappzoo/tree/master/tensorflow/mobilenets
But when I ran 'make', the error happend:

Please help me to solve this problem. I also cannot run 'make examples' after the installation.

  • Hi @Meow10

    Thank you for reaching out! Could you please provide additional information about your setup?

    • Are you using the NCSDK1 or NCSDK2? (version 1.12, 2.08 or older)
    • Which branch did you clone of the ncappzoo repository? (ncsdk2 or master)
    • Are you using the original Neural Compute Stick or the Neural Compute Stick 2?
    • Is the device listed when running lsusb?
    • Are you running Ubuntu as a virtual machine?
    • Have you tried connecting the device to a powered USB Hub or a different USB 3.0 port?

    Regards,
    Jesus

  • @Jesus_at_Intel The following are the answers to your questions:
    1. NCSDK2 2.08.01.02
    2. master
    3. the Neural Compute Stick 2
    4. The device is listed when running Isusb.
    5. Ubuntu
    6. I haven't tried.
    Thank you!

  • Hi @Meow10

    You will need to use the OpenVINO toolkit with the Intel Neural Compute Stick 2 as the NCSDK only support the original Neural Compute Stick.
    Take a look at the Get Started Guide.

    Hope this helps!

    Regards,
    Jesus
