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

idata — Thu, 20 Dec 2018 02:22:05 GMT

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]
