How to get readings from HE Magnetic keyboard (exmp Fun60)?

How to get analog readings from HE Magnetic keyboard for example Fun60?
i tried sniff hid but it show nothing.

Assuming that it’s treated like every other keyboard, you should be able the standard keyboard APIs. They are not exposed as USB HIDs, as that would be a massive hole in your security; Every user on your machine can read your HID input.

As i know Fun60 not expose its HID, but i was hoped that there is way to measure USB packet size len() for example low size starting readings show low size packet len and maximum deep key travel show maximum size packed, but it seems it’s not working.
Interesting thing that Wooting60 have open code and can be easily exploited.
