Using 2 separate stiles for curly brackets. Please put the opening and
closing brackets on separate lines. It makes it so much easer to read. Ex:

if (something)
{
  /* Doing something */
}
else
{
  /* Doing something else */
}

In xinput.h you adding lots of defines you not using. And you just threw all
of them together in one big pile. Please add them when you need them. Or at
least put them into proper groups.

Why 4? Why not 40? Have you run your tests on windows?

You should call it the right way from the start.
