The keyboard lighting on an Alienware m15 is controlled over raw HID, and none of the existing tools — OpenRGB, AlienFX, AKBL — drive it. Rather than live with it, I worked out the command set from the device's own HID report descriptor, with the open-source AlienFX-SDK as a reference, and wrote a driver.
It addresses lights by ID rather than by key: it does fills and zones well, and "make the W key red" is still a TODO, because mapping light IDs to physical key positions is its own project.
Four tagged releases, and it is public — one of the few things here a stranger can read the source of and run.
