rpi5-64 (Raspberry Pi 5 64-bit OS) image and Pineboard Coral Edge TPU

Describe the issue you are experiencing

I am not sure if this is a home-assistant operating-system issue, Frigate or a Google Coral issue, so I also posted this here.

Basically, when installing a Raspberry mPCIe Coral Edge TPU or a Dual Edge Coral TPU with the corresponding Google Coral (Dual) Edge TPU on a Pi5 it is my opinion that this should work in Frigate when changing the detector from cpu to edgetpu in the frigate config file.

I got the famous Permission checking failed error for the apex device in the dmesg, so I tried to add a /etc/udev/rules.d/65-apex.rules file to set mode to 0660 for root:root. That error is now gone.

What operating system image do you use?

rpi5-64 (Raspberry Pi 5 64-bit OS)

What version of Home Assistant Operating System is installed?

Home Assistant OS 12.3

Did you upgrade the Operating System.

Yes

Steps to reproduce the issue

1. Have a working Frigate Add installation running a CPU detector.
2. Connect a Pineboards Hat AI! Dual Edge Coral TPU Bundle for Raspberry Pi 5
3. Boot the Home Assistant Pi
4. Check the Frigate addon is working using the CPU type detector.
5. Change the config in Frigate.yaml from CPU to edgetpu: ...

Additional information

When I search the internet, I find things about device tree sets up and the PCIe bus to not have enough MSI-X interrupts? This is a bit too in depth for how much I know about Linux at this point. Advice is welcome.
