Hi everyone,
I don’t acheive to make my Google Coral USB work for my frigate installation. I’m not sure to be in the good topics so if i’m wrong don’t hesite to tell me 
This is my installation for now:
- Hardware : Intel NUC
- Software :
- Proxmox installed on it
- VM for Home Assistant
- LXC for frigate and Portainer on it to launch frigate container.
I follow this tuto : https://www.saninnsalas.com/passing-google-coral-usb-edge-tpu-to-an-unprivileged-container-in-proxmox/
Then I modified my docker image like this :
version: "3.9"
services:
frigate:
container_name: frigate
privileged: true # this may not be necessary for all setups
restart: unless-stopped
image: ghcr.io/blakeblackshear/frigate:stable
shm_size: "256mb" # update for your cameras based on calculation above
devices:
- /dev/bus/usb:/dev/bus/usb # passes the USB Coral, needs to be modified for other versions
#- /dev/apex_0:/dev/apex_0 # passes a PCIe Coral, follow driver instructions here https://coral.ai/docs/m2/get-started/#2a-on-linux
- /dev/dri/renderD128 # for intel hwaccel, needs to be updated for your hardware
volumes:
- /etc/localtime:/etc/localtime:ro
- /opt/frigate/config.yml:/config/config.yml
- /opt/frigate/storage:/media/frigate
- type: tmpfs # Optional: 1GB of memory, reduces SSD/SD Card wear
target: /tmp/cache
tmpfs:
size: 1000000000
ports:
- "5000:5000"
- "8554:8554" # RTSP feeds
- "8555:8555/tcp" # WebRTC over tcp
- "8555:8555/udp" # WebRTC over udp
#environment:
# FRIGATE_RTSP_PASSWORD: "password"
And finally I modified my Frigate configuration file with this :
detectors:
coral:
type: edgetpu
device: usb
With this configurations I have my frigate container which is loop in “start, error and stop” with this mesage :

Could you tell me what I’m doing wrong ? Do I miss something on configuration side ?
Thanks you very much for your help.
