I would like to be able to detect DirectInput from a controller from which Windows does not even detect buttons. It's a Bluetooth controller, Windows detects it and accepts it as a controller, but it just does not do anything. Steam actually has a way to recieve the input from this controller but I want to do that on my own without depending on Steam.

I need a small start to know how to detect DirectInput.

I also tried x360ce. But there again, it does not detect any input. The controller is detected but not responding, so, I want to make my own DirectInput to XInput without all of the huge configurations and options.

It looks more complicated than I thought ( I did a little searching out of curiosity ). Seems like there is a service to translate the bluetooth to a HID like device.

This method looks to be more direct:

Hmmm...I'm getting out of my old programming habits and I forgot that LOL. I know ASM will make you do everything manually, I just did not happen to think about the Bluetooth connectivity, that's dumb of me. I was thinking about simply using a DLL call from windows or something like that and simply do an import of prewritten calls. Well then, I will dig deeper, as usual. Thanks for your help and link.
