From what I can tell, it is meant to be possible to query device data (For joysticks at least) to obtain device capabilities (ie number of axes and buttons).

This is implemented via passing RIDI_PREPARSEDDATA to GetRawInputDeviceInfo.

Further calls to HID.dll are then made (eg HidP_GetCaps) to determine the capabilities of the device.

I am trying to work through adding this functionality, but it is not something I know much about. Any help appreciated.

Hello, Sir.
I have troubles with understanding the documentation, could you please point me to the right direction?

I have a "laptop" with keyboard and touchpad. Unfortunately, the touchpad is somehow "hacked" by chinese manufacturers, so it has smart gestures emulated. So whenever I swipe left on touchpad, it sends "Left Windows" button.
As far as I see, I can try filtering such buttons by getting DeviceID of keyboard & touchpad and simply ignoring "Left Windows" sends by touchpad.

GetDevInfo function requiers an index. However is there any way to get device which send a specific button?

I understand a couple of others may have worked on this code in the AHK forums, but it would be nice if this library had a clear license or even some short verbal indication of the ability to re-use this code in other projects.

I have a project that could have benefited from this library, but I also want to ensure that I respect the wishes of the author(s). What I have is an open-sourced project, GPL v2 (although I am fine with other licenses such as MIT & even GPL v3, if asked), but may issue with including ambiguously licensed code comes down to distros and distribution.

My project spans across Windows and Linux. I guess if I were to use this code I could download it separately, if needed on Windows.

code in examples unreadable and full of magic. It is not clear, what it is doing.
For example:

;Anchor by Titan, adapted by TheGood
;http://www.autohotkey.com/forum/viewtopic.php?p=377395#377395
Anchor(i, a = "", r = false) {
    static c, cs = 12, cx = 255, cl = 0, g, gs = 8, gl = 0, gpi, gw, gh, z = 0, k = 0xffff, ptr

May be add more of simpler exaples?

When i execute example_1.ahk i always just get
