Cannot control keyboard backlight on Asus FX505DY

I am not able to control the keyboard backlight in my laptop (ASUS FX505DY). The output of lsmod | grep asus is

asus_nb_wmi            28672  0
asus_wmi               32768  1 asus_nb_wmi
sparse_keymap          16384  1 asus_wmi
rfkill                 28672  9 asus_wmi,bluetooth,cfg80211
wmi                    32768  2 asus_wmi,wmi_bmof
asus_wireless          20480  0
i8042                  32768  1 asus_nb_wmi

asus-nb-wmi is loaded but I can't find asus::kbd_backlight in /sys/class/leds/

Output of ls /sys/class/leds is

asus-wireless::airplane  input6::capslock  input6::numlock  input6::scrolllock

Output of dmesg | grep asus is

[    9.421619] asus_wmi: ASUS WMI generic driver loaded
[    9.456057] input: Asus WMI hotkeys as /devices/platform/asus-nb-wmi/input/input14
[    9.470693] asus_wmi: Number of fans: 0

Have you tried the D-Bus method for adjusting your keyboard backlight?

Yes I have tried that. It gives me the error

No such interface “org.freedesktop.UPower.KbdBacklight” on object at path /org/freedesktop/UPower/KbdBacklight

I guess the kernel module asus-nb-wmi doesn't support my laptop model (Asus FX505DY) yet.

Did you enable/start upower.service before trying to run the script?
