xlat VS hidapi

Finalmouse just released its new latency measurement tool, the XLAT, which is supposedly more accurate than the Nvidia LDAT for measuring mouse latency. https://github.com/teamfinalmouse/xlat

On the computer, write a program (the "host" or "server") that talks over the raw HID protocol. It is open ended how you do this, but IME both the Python pyhidapi and C hidapi were simple enough to get something started. The trickiest part might be getting the program to run with the permissions to talk the raw HID protocol (at least on Linux, there was some udev rule to set up). Read the documentation for these libraries for details about how to get set up.

now I'm trying to figure out what to do with the next step for building my own host. Am I supposed to put this test file in my qmk code? or run it on my computer as it's own separate program? https://github.com/libusb/hidapi/blob/master/hidtest/test.c

HIDAPI

I did star https://github.com/libusb/hidapi too, as well as this GitHub.

I used ffigen to get the bindings from hidapi.h and cleaned up quite some of the resulting output to make it Dart compatible. Quite some typedef and some minor stuff.

I figured out the problem with JoyconLib! The hidapi.dll file was broken so I replaced it with a new file from https://github.com/libusb/hidapi/releases and not it's working.

Inspired by https://askubuntu.com/questions/699138/logitech-k380-bluetooth-keyboard-make-function-keys-default and https://github.com/libusb/hidapi, it's almost re-implementation of hidapi actually, with dart:ffi calling the syscall directly.
