Hi everyone,
I post my problem on german forum aswell…
I’m trying to get the Google Coral USB Accelerator working with Frigate on my Raspberry Pi 5, but it’s not being detected by Frigate. I hope someone can help me.
My Setup:
- Raspberry Pi 5
- Home Assistant OS 17.1
- Home Assistant Core 2026.3.3
- Frigate Full Access Add-on v0.17.1
- Google Coral USB Accelerator
- Official Raspberry Pi 27W USB-C Power Supply
What works:
- The Coral is visible in lsusb as: Bus 004 Device 003: ID 1a6e:089a
- Protection mode is disabled on Frigate Full Access
- Windows shows usb device in DFU mode
The problem:
- Frigate always falls back to CPU detector
- The Coral does NOT appear on the Hardware page in HA Settings
- chmod on /dev/bus/usb/004/003 fails with: Read-only file system
My Frigate config (/homeassistant/frigate/config.yml):
mqtt:
host: core-mosquitto
detectors:
coral:
type: edgetpu
device: usb:/dev/bus/usb/004/003
cameras:
test:
ffmpeg:
inputs:
- path: rtsp://…
roles:
- detect
detect:
width: 640
height: 360
Frigate log shows:
INFO: Created TensorFlow Lite XNNPACK delegate for CPU.
WARNING: CPU detectors are not recommended and should only be used for testing or for trial purposes.
What I have already tried:
- Frigate Full Access with Protection mode disabled
- Direct USB connection and powered USB hub
- device: usb, device: usb:0 and device: usb:/dev/bus/usb/004/003
- Multiple reboots
- Different USB ports
Has anyone solved this on HAOS 17.1 with Raspberry Pi 5?
Thank you!
