M.2 Coral with Docker Rootless Frigate

[YellowCushion]

Description

I have Docker Rootless running on Ubuntu Server 20.04.5 LTS with a M.2 Dual Edge TPU.

I can run inference on the host (in line with https://www.coral.ai/docs/m2/get-started/#4-run-a-model-on-the-edge-tpu).

Frigate is stable with CPU detector in my config file but constantly restarts when I try to use my Edge TPU.

I have seen similar topics regarding USB Corals which talk about updating the udev rules to allow non-root users to access USB. I think my udev rules are correct. /etc/udev/rules.d/nano 65-apex.rules:

SUBSYSTEM=="apex",` MODE="0660", GROUP="apex"

I have previously posted this on the Frigate project and the dev there came to the conclusion it's a udev issue and I would be better posting here for support.
