Hi,
I am testing my NCStick in Ubuntu 16.04 on virtualbox 5.2.12. Following the post to modified the example but got a NCS initialization error:

I have re-generated a new squeezenet1.1 model with FP16, and modified parameters in "demo_squeezenet_download_convert_run.sh" bash file.
Here is the log:

Hi DaveW,
Can you setup Movidious driver for Windows following instruction and try again from virtualbox?
<your openvino installation directory>/deployment_tools/documentation/PluginMyriad.html
If you can't find "PluginMyriad.html", please go to c:\intel\computer_vision_sdk_xxxx\deployment_tools\documentation.
And please open "index.html" with google chrome or internet explorer.
Please look for "MYRIAD" and click.
You should setup Movidius driver manually in Windows.
Regards,
Peter.

I installed OpenVINO on my host Windows 10 machine and duplicated the procedure (including modifying .bat file) to run the executable today. Still got a similar problem.

Hi Anna,
Yes. Before running the example, I had set up USB rules on my Ubuntu virtual machine. Do I need to also set up it on my host Windows machine?
It seems that my NCStick was detected normally when plugging in to both environments. However, something went wrong at the initialization stage.
Thanks.

Hi,
Could anyone give some suggestion? I have no idea how to deal with the problem. Is it a hardware compatible issue?
Thanks

Hi SEUNGHYUK,
Thanks for your information. By following the instruction of updating driver in Windows, now the example can run on Movidius NCStick in my Windows 10 environment.
Just provide an additional information, in my Win10, there was one more step to select device between picture-2 (browse software driver on computer) and picture-3 (select driver) when updating driver. NCStick is in "Universal Serial Bus Device".

Hi SEUNGHYUK,
Excuse me for bothering you again. I found that it still didn't work on my Ubuntu virtual machine.
USB rule and adding to users group were all set. After the first execution, NCStick changed detected name into "VSC Loopback Device" again. In the situation, I can solve it by updating driver in Windows. However, I don't know how to provide a similar way to do so in Ubuntu. Is there a similar method to update driver in Linux??
All my works are done in Ubuntu so I really hope NCStick can work in Linux.
Thank you.

Hi DaveW,
Good to hear that you found solution in windows.
Did you install and setup virtual env after you setup NCStick USB rules?
If not, can you keep the sequence?
Enable NCStick and install virtual machine.
I have a question.
Why don't you do not use virtual machine and test from real machine for now?
Regards,
Peter.

Hi Peter,
What kind of installation and setup I need to do in Linux virtual machine for the NCStick?
I've enable USB 3.0 and added USB filter from Virtualbox setting so that my virtual machine can detect NCStick and successfully run NCSDK/NCAppzoo examples in Ubuntu. OpenVINO example can also execute with CPU as inference machine.
I am working on developing a neuron network and deploying it into a standalone platform (like Raspberry Pi). NCStick as an accelerator for inference is necessary because platforms might be too slow. However, I just found a post:
https://software.intel.com/en-us/forums/computer-vision/topic/781076
Doesthat mean I cannot install OpenVINO in Raspberry Pi and use API on the platform loading data into NCStick??
Thanks.

Hi Dave,
Here are the following instructions to get the virtual machine working with the NCStick.
Theoretically, you could if you had the proper libraries needed but this hasn't been tested as this isn't part of our supported hardware types that have been tested.
Kind Regards,
Monique Jones

Hi Monique,
Thanks for your link. That instruction is useful for setting up the NCStick with NCSDK. I also followed that in my 1st installation. Hence, my NCStick can run NCAppzoo examples with NCSDK in virtual machine (Ubuntu) successfully.
However, once I used OpenVINO API to initial NCStick. My NCStick became unrecognized after OpenVINO tried to access it. In the situation, NCSDK also could not access to the stick.
The way Peter provided to me above exactly solved the problem in Windows 10: When NCStick becoming unrecognized, we can update its driver manually. Then, Windows 10 recognizes NCStick forever and everything works fine. Nevertheless, it's not the same in Linux virtual machine. Once VirtualBox is running, USB devices use VirtualBox driver instead of its own driver. I couldn't update driver in the manner because devices need virtual box driver to be plugged into virtual machine. Hope someone has the idea to solve it.
By the way, is that OpenVINO doesn't support Raspberry Pi (ARM structure)? I would like to double check this. If it is true, I might need to stop here and think another way to do.
Thanks.
Dave
