I recall someone who build some automated system to measure input latency on gamepads, who gathered data for a bunch over different interfaces, which is a subset of that. They had some sort of automated testing system, moved the controls automatically with a microcontroller-driven system.

Neither of them are what I'm remembering, but it looks like multiple people have built input latency databases.

The second looks close to what you might want. Each controller has a page with a fair amount of information.
EDIT: I don't think that this is what I was thinking of either, but looks like another microcontroller-based system to measure input latency:

EDIT2: Also not what I was thinking of, but yet another input latency measurement project:

That's some good data! I'm mostly interested in filtering by Linux support and latency/accuracy measurements. Some of them are very helpful, thank you!
