Claude did most of the debugging of a Coral TPU that Frigate couldn't initialise on HAOS on a Pi 5; the fix was using the TPU's full PCI address.

The full story
Every guide said to use a generic device setting for a Google Coral PCIe TPU in Frigate, but on Home Assistant OS on a Raspberry Pi 5 that failed with "No EdgeTPU was detected", even though the drivers loaded. The poster says Claude.ai helped with most of the debugging and Gemini got him over the line.
The fix was to give Frigate the TPU's full PCI bus address. The write-up, which he had Claude summarise, explains how to find that address from the HAOS SSH terminal.
