## Issue description Keyboard backlight not working on Asus TUF Gaming A16 2024 (FA608WI). Version with Ryzen AI 9 HX 370 and Geforce RTX 4070. ## Steps to reproduce No "bug" output, just the fact that asusctl -k high return no error, but no backlight turn on (same things with keyboard shortcuts and gnome control panel). Asus_smi is loaded, /sys/class/leds/asus::kbd_backlight/brightness is correctly edited (0 to 3) but nothing change on keyboard. ## What is the current bug behavior? No backlight on keyboard. ## What is the expected correct behavior? Backlight must turn on or off with keyboard shortcuts, asusctl or gnome control panel. ## Relevant logs and/or screenshots [asusd.log](/uploads/d023ba4b70e83af8b4d2640737d508aa/asusd.log) lspci : ```00:00.0 Host bridge: Advanced Micro Devices, Inc.
