Greetings support,
I am runing into this error "E: [ncAPI] [ 4990] ncDeviceOpen:800 Failed connection to device (1.1-ma2480) with error 5" When I run this "./demo_squeezenet_download_convert_run.sh -d MYRIAD". As expected it run fine when using the CPU "./demo_squeezenet_download_convert_run.sh".
I am using the Intel NCS2 on an Ubuntu 16.04 virtual box 6.0.8, and the host machine is a MAC 10.13.6. I have already tried the suggestions in this topic (https://software.intel.com/en-us/forums/computer-vision/topic/805215) and they did not work. Here are my rules settings:
VirtualBox:~$ cat /etc/udev/rules.d/97-myriad-usbboot.rules
SUBSYSTEM=="usb", ATTRS{idProduct}=="2150", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0666", ENV{ID_MM_DEVICE_IGNORE}="1"
SUBSYSTEM=="usb", ATTRS{idProduct}=="f63b", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0666", ENV{ID_MM_DEVICE_IGNORE}="1"
SUBSYSTEM=="usb", ATTRS{idProduct}=="2485", ATTRS{idVendor}=="03e7", GROUP="users", MODE="0666", ENV{ID_MM_DEVICE_IGNORE}="1"
Any help will greatly be appreciated.
Thank you in advance.

Hi Jerry,
It's possible the Virtual Machine is not picking up the loopback device. Could you check your USB filters and that USB 3.0 is enabled on the virtual machine settings?
You should have a filter with the following, everything else can stay blank:
Name: Movidius Myriad X Vendor ID: 03e7
Also, which version of the OpenVINO toolkit are you using? After I executed the following commands from the getting started guide, I had to log out and back in for the demo's to run.
source ~/intel/openvino/bin/setupvars.sh cd ~/intel/openvino/install_dependencies ./install_NCS_udev_rules.sh
Hope this helps!
Regards,
Jesus

Hi Jesus,
Yes, I believe the VM is properly setup please see attached image. The OpenVino toolkit version is "openvino_toolkit_p_2019.1.144"
$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 013: ID 03e7:2485
Bus 001 Device 012: ID 80ee:0021 VirtualBox USB Tablet
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
when you run the example like "./demo_squeezenet_download_convert_run.sh -d MYRIAD" it seems to disconnects. I have to reconnect it using Devices>USB on the VM.
Thank you.

Hi Jerry,
Try removing everything from your filter except the name and vendor id. I believe the VM is not picking up the loopback device after the device resets. The NCS will reset after the model is loaded and should reconnect automatically to the system. It will have the same vendor ID but I believe the product id changes.

Jesus

Hi Jerry,
When the Neural Compute Stick reboots after the model is loaded, it will have a different Product ID. By leaving the Product ID blank, the filter will look for any device with the vendor ID.
Hope this helps!

Hi Jesus
I am the fresh men who study the NCS, I had the same problem. I have no idea about "try removing everything from your filter except the name and vendor id". could you please teach me how to operate it in detail? Thank you very much.
