[Error 7] Toolkit Error: USB Failure. Code: No devices found

[Error 7] Toolkit Error: USB Failure. Code: No devices found

 

I have Googled this and seen that it is a problem, but I have yet to find fix for it.

 

So I am at a dead end and looking for ideas.

 

Windows 10

 

Boot windows - plugin Movidius

 

Universal Serial Bus devices

 

Movidius MA2X5X

 

 

This device is working properly.

 

Port_#0009.Hub_#0003

 

Device USB\VID_03E7&PID_2150\03e72150 was not migrated due to partial or ambiguous match.

 

 

Unbunto 16.04.5

 

Start in VirtualBox 5.2.22

 

Windows 10 removes Movidius MA2X5X from Device Manager

 

 

Devices > USB = Movidius Ltd. Movidius MA2X5X [0001]

 

$ lsusb = Bus 001 Device 003: ID 03e7:2150 Intel Myriad VPU [Movidius Neural Compute Stick]

 

 

$ make example

 

 

W: [ 0] ncDeviceOpen:565 failed to find device

 

[Error 7] Toolkit Error: USB Failure. Code: No devices found

 

Makefile:64: recipe for target 'profile' failed

 

make[3]: *** [profile] Error 255

 

make[3]: Leaving directory '/home/michael/ncsdk/examples/caffe/AlexNet'

 

Makefile:12: recipe for target 'AlexNet' failed

 

make[2]: *** [AlexNet] Error 2

 

make[2]: Leaving directory '/home/michael/ncsdk/examples/caffe'

 

Makefile:12: recipe for target 'caffe/.' failed

 

make[1]: *** [caffe/.] Error 2

 

make[1]: Leaving directory '/home/michael/ncsdk/examples'

 

Makefile:57: recipe for target 'examples' failed

 

make: *** [examples] Error 2

 

 

After fail

 

 

Devices > USB = Intel Corporation VSC Loopback Device [0100]

 

$ lsusb =

 

 

Unplug USB put it back in

 

 

Devices > USB = Movidius Ltd. Movidius MA2X5X [0001]

 

$ lsusb = Bus 001 Device 008: ID 03e7:2150 Intel Myriad VPU [Movidius Neural Compute Stick]

 

 

Now shutting down the VM, Windows Device Manager picks up the USB again, but now as

 

 

VSC Loopback Device

 

This device is working properly.

 

Port#0020.Hub_#0003

 

Device USB\VID_03E7&PID_F63B\DDB85DD574E708 was not migrated due to partial or ambiguous match.

 

 

Relaunching Unbunto at this point

 

 

Devices > USB = Intel Corporation VSC Loopback Device [0100]

 

$ lsusb =

 

 

Removing USB and plugging it in returns Unbunto to

 

 

Devices > USB = Movidius Ltd. Movidius MA2X5X [0001]

 

$ lsusb = Bus 001 Device 003: ID 03e7:2150 Intel Myriad VPU [Movidius Neural Compute Stick]
