Coral USB keeps on crashing

[Rob8]

I did a clean installation of Proxmox VE 9.1.1, and are trying to run frigate on a LXC container and utilizing the coral USB TPU. Unfortunately, the Debian 13 keeps on crashing, it is the same with USB2 or USB3 port.

Plugin to the USB2 port

Hopefully someone can help out fixing this?

Hi,

IT can fails in your LXC setup because the Coral USB driver (apex/gasket) requires direct kernel-level USB access, but your container is unprivileged and only bind-mounts /dev/bus/usb, which causes driver conflicts and crashes on Debian 13.
The TPU works reliably only with privileged VM passthrough where the USB device is exposed directly to the guest OS.
