USB disconnect while building the examples

In the bin directory of the mvnsdk I do:

 

make example01

 

echo "example01 - GoogleNet profiling"

 

example01 - GoogleNet profiling

 

python3 ./mvNCProfile.pyc data/googlenet.prototxt -s 12

 

mvNCProfile v02.00, Copyright @ Movidius Ltd 2016

Hi,

 

Similar issue here : SDK installed without troubles in VBox. When trying to build the Tensorflow inception_v1 example, the USB NC stick lost its USB connection, and the build fails with error "[Error 7] Toolkit Error: USB Failure. Code: Error opening device"

 

Configuration : Windows Enterprise 7 Host, Virtual Box 5.2.0 with Extension Pack installed, Ubuntu 16.04 LTS (fully up-to-date, Kernel 4.10.0-28-generic #32~16.04.2-Ubuntu).

 

Also, following the documentation https://movidius.github.io/ncsdk/VirtualMachineConfig.html : I can add a filter "USB2 filter with vendor ID 03e7 and product ID 2150" but VBox does not see "USB3 filter with vendor ID 040e and product ID f63b" (the laptop is a recent model and support USB3.0 devices. I can mount in the Ubuntu VM a flash disk in USB3.0 mode without any trouble)

 

I have tried to plug the NC Stick in a USB3.0 hub but it does not help.

 

(I will try to build on a Pi3 with Raspian Stretch : I missed to read the documentation https://movidius.github.io/ncsdk/install.html, and tried to install on a Ubuntu mate 16.04 .. .. which faills during SDK installation)

@georgievm_cms Thanks for the link !! That's very helpfull to know that we can/have to enable both USB 2 and USB3 suppor at the same time ! The VBox GUI is not clear at all on this possibility (bad UX) . After a couple of tries, I did noticed the change in my VM's [VM Name].vbox configuration file (-> OHCI and EHCI entries in the controllers section)

 

<USB> <Controllers> <Controller name="OHCI" type="OHCI"/> <Controller name="EHCI" type="EHCI"/> </Controllers> <DeviceFilters> <DeviceFilter name="Movidius USB3" active="true" vendorId="040e" productId="f63b" remote="0"/> <DeviceFilter name="Movidius USB2" active="true" vendorId="03e7" productId="2150" remote="0"/> </DeviceFilters> </USB>

 

(Note : if you want to edit this configuration file manually, make sure VBox is not started first, as it might overwrite your changes at any time)

 

However, I also found yesterday evening that the host on which I was testing does not meet the minimum requirements for the NC stick -> Windows 10. (I was testing on a Windows 7 system…but actually it looks like there are issues with USB 3 / Windows 7 / VBox, at least for Win 7 guest as described here : http://www.virtualbox.org/manual/ch12.html#idm11250)… …. but maybe this might also affect Win 7 as host (??) … anyway I'll have to find another way to test !

Did you ever get a reply and a solution. I have the same problem on a new Movidius 2 and the latest build of Openvino
