When i execute example_1.ahk i always just get

---------------------------
example_1.ahk
---------------------------
Error:  Call to nonexistent function.

Specifically: AHKHID_UseConstants()

	042: HID%HID0%_Name := AHKHID_GetDevName(HID0)

The program will exit.

You need to include the library in your code.

Download AHKHID.ahk to the same directory as example_1.ahk: https://github.com/jleb/AHKHID/raw/master/AHKHID.ahk
Add `#include AHKHID.ahk' to the top of the example.

This begs the question "Why don`t the examples already contain this line in them?" You never want examples to require setup.

Ran into same problem, suggested fix worked.
