I don't really want to use a USB TPU (no real reason)

Since there is no real reason, why no reevaluate?

I connected my USB TPU to a spare internal USB 3.0 header and mounted it inside the case. Frigate has been working perfectly fine for years.

I also use quite a few PCIe M.2 adapters but only for SSDs. No complaints here, full transfer speed and reliable. No reason why it shouldn't work for TPUs.

I'd have to dig through my Amazon orders, but I ran one such adapter in my work desktop for a while.

Just read the 3 and 4 star reviews and go from there

Do you need a TPU? If you have a 7th gen or later Intel iGPU you can use OpenVINO in frigate and it works just as well if not better.

I use a ton of pcie adapters at work, but not really sure what you are doing? Pcie to m.2? Almost all the ones I've used off of amazon have worked fine except a sabrent one, it worked fine for a m.2 drive to have an os but when I used it for testing drives it didn't work, it also took up a whole x16 slot for no raisin

We use ones that look like this
