[Device Support]: No keyboard backlight on ASUS TUF Gaming A16 FA608PP (WMI/DSTS path, no HID handshake)

[Kunal19xx]

1. System & Device Information

**Model:** ASUS TUF Gaming A16 FA608PP
**Distro/Kernel:** CachyOS, linux-cachyos 7.1.5-1
❯ asusctl info
asusctl v6.3.11

Software version: 6.3.11
  Product family: ASUS TUF Gaming A16
      Board name: FA608PP

Keyboard backlight does not work on cold boot to Linux.
Booting Windows first, then rebooting to Linux, fixes it for that session.

- Manual sysfs write works with no error (0-3) but no physical effect until Windows has booted first.
- `aura_support.ron` had no entry for FA608PP — added one (layout "fa608", same as sibling FA608PM) — no change in behavior.
- `dmesg | grep hid-asus` shows zero handshake activity — this board uses the older asus-nb-wmi/ATK (DSTS) path, not the HID handshake path the recent "HID: asus: Fix ASUS ROG Laptop's Keyboard backlight handling" series targets.
- dmesg confirms: "asus-nb-wmi: Detected ATK, not ASUSWMI, use DSTS"

Please follow #119

[NeroReflex]

I2c is fully supported, the only issue is that it boots in lamparray on.

There is another issue about those modern tuf opened: find that and read it as it contains a workaround and the plan for the (hopefully) near future.

[Ghoul4500]

This likely is lamparray as Nero said but there exists a second report of backlight working on this model here: #225

Could you please edit the file at /usr/share/asusd/aura_support.ron as mentioned in this issue and confirm for us whether or not this fixes it? If not, we can confirm the fix only exists via lamparray implementation in the kernel
