Discussion on: Coral EdgeTPU USB Accelerator with VirtualBox

After some digging, this is what I found with VMWare Fusion (and I guess VirtualBox is something like this):

  • plug in the Coral USB accelerator
  • start VMWare Fusion
  • start the (Ubuntu/Debian) VM
  • in the VM settings, attach the "Global Unichip device" to USB
  • run the engine (classify or detection)
  • it will fail with "RuntimeError: Failed to allocate tensors"
  • in the VM settings, remove the Global Unichip device from USB. DO NOT UNPLUG!
  • you will see it suddenly becomes "Google USB Device"
  • in the VM settings, attach the "Google USB Device" to USB
  • and all is well

It just needs an init from a first run and a forced logical disconnect from the original device.
Instead of disconnect, a VM reboot sometimes also works, but it's not always successful.
Any physical power down of the device will force you to go through the process again.

It might be possible to automate this.

F.I.:

Initially, both the VM and the host (MBP in my case), show the USB device as:

Product ID: 0x089a
Vendor ID: 0x1a6e (Global Unichip Corp.)

After the "init + re-attach", both show the USB device as:

Product ID: 0x9302
Vendor ID: 0x18d1 (Google Inc.)

I have reached out to Google for guidance on making this easier.
