Google Coral USB changing ID/Vendor

[bluepr0]

Hello!

I have a container setup with Frigate and I'm experiencing a weird issue where my USB ID and Vendor ID are changing after setting up UDEV rules

If I do an lsusb I get

Bus 002 Device 002: ID 1a6e:089a Global Unichip Corp.

Then I configure the USB using the previous information

root@proxmox:~# nano /etc/udev/rules.d/98-coral.rules

SUBSYSTEMS=="usb", ATTRS{idVendor}=="1a6e", ATTRS{idProduct}=="089a", OWNER="root", SYMLINK+="coral", MODE="0666", GROUP="plugdev"

Container config

root@proxmox:~# nano /etc/pve/lxc/102.conf

GNU nano 5.4

lxc.cap.drop:
lxc.mount.auto: cgroup:rw

I restart the server and when it's back and I do a lsusb I get

Bus 002 Device 003: ID 18d1:9302 Google Inc.

I have to edit the UDEV rule again and then it works fine. But sometimes when I turn off the server or restart it. it goes back to the previous ID and I have to repeat the process.

Any ideas on what's going on? Thanks!

Exact same issue here but restarts don't seem to be "initialising" the Coral. Would love some ideas to try.

@Rebem here's an idea the guys from Coral suggested https://github.com/google-coral/edgetpu/issues/536 haven't tried it yet but let me know if it helps fix it!

Thanks bluepr0 - I should have given more context for my use case - this is correct for a VM but I'm using it in an LXC. However I've found that the problem is linked to first initialisation of the Coral like that article says. Embarrassingly I think my issue was I passed through USB Bus 4 instead of 3 and now it's working fine!
