Error when trying to use Coral USB edgetpu

Error:

My config:

I'm using a Proxmox host to passthrough my VM that hosts a bunch of docker containers. Which is another layer of potential issues, but I've been able to do usb passthrough with a aeotec z-wave usb controller.

This is what lsusb looks like on the VM

Bus 001 Device 007: ID 1a6e:089a Global Unichip Corp. 
Bus 001 Device 003: ID 0624:0249 Avocent Corp. Virtual Keyboard/Mouse

Bus 002 Device 002: ID 0627:0001 Adomax Technology Co., Ltd

Do you have any advice?

Nvm, looks like after installing drivers on host and vm, not sure if both was necessary... I was able to redo the passthrough, restart the vm and lsusb looks like this:

Bus 001 Device 004: ID 18d1:9302 Google Inc. 
Bus 001 Device 003: ID 0624:0249 Avocent Corp. Virtual Keyboard/Mouse

Everything is working now :D

Yeah, you usually just use --device /dev/bus/usb and the first time it runs it actually installs some driver and it changes from Global Unichip to Google and it will sometimes fail to start doods. If you have docker automatically restart the container then it goes.

Yeah also running it with --device /dev/bus/usb now too. Thanks for setting this package and docker up. Very easy to use!
