"No devices found" with ncs

Hi.

ncsdk 'make install' was done. Running 'make examples', could see error '[Error 7] Toolkit Error: USB Failure. Code: No devices found'
Using Ubuntu 16.04 on Virtual box/Windows10. ncs was detected as “MA2X5X serial no. 03E72150” Would you please advise how to fix this error ?

  • @mssong Please make sure that you have the following configurations specified at VM config and make sure you have set both USB filters (It looks like you already have at least one filter). Two filters are needed because the NCS device switches from USB2 to USB3 when being accessed. Please post your dmesg/lsusb logs here when plugging in the NCS device and trying to run the hello_ncs app.

    hatem@hatem-Dell:~/workspace/ncsdk/examples/apps/hello_ncs_py$ make run

    making run
    python3 hello_ncs.py;
    Error - no NCS devices detected, verify an NCS device is connected.

    But still i can't ping the stick.
    I tried both ncsdk and ncappzoo

    Thank you for your help

  • Hi @hatem_K

    The Intel OpenVINO toolkit is the default software development kit for the Intel Neural Compute Stick 2. The NCSDK only supports for the original Neural Compute Stick.

    You will need to download and install OpenVINO using the following instructions:
    https://software.intel.com/en-us/neural-compute-stick/get-started

    You can find additional information on the OpenVINO Forums:
