[Bug]: Backlight doesn't turn on Zenbook UX3402VA

[ivan0rdonez]

Describe the bug

I run PopOS 22.04 LTS on a Zenbook UX3402VA_UX3402VA. I installed executing bash install.sh without errors but the backlight of the numpad/mousepad never turned on.

I discover that the padnum does actually work since I can input numbers and symbols with the touchpad after long pressing the top right corner.

I tried the faq's steps, I executed bash install_device_check.sh to get the device id and address, they are the default ones, and tried to send different signals as recommended to no avail:

i2ctransfer -f -y 1 w13@0x15 0x05 0x00 0x3d 0x03 0x06 0x00 0x07 0x00 0x0d 0x14 0x03 0x60 0xad
i2ctransfer -f -y 1 w13@0x15 0x05 0x00 0x3d 0x03 0x06 0x00 0x07 0x00 0x0d 0x14 0x03 0x01 0xad

And also bright levels.

I noticed an error in the /var/log/asus-numberpad-driver/error.log

Finally I tried with the recommended layout (ux433fa) but it doesnt look like the one in my instruction booklet or the pictures of the asus store, since I never booted windows I don't know for sure, so I tried withup5401ea.pyand[up5401ea-3145.py` since it is the one that looks more similar to the manual, but indeed the mapping is different.

Expected behavior

Backlight should turn on when I longpress the upper right corner of my mousepad

@ivan0rdonez Hello, thank you for creating an issue. What was the output of $ bash install_device_check.sh? Could you post it here? Was the address of i2c register 0x15? Are you sure device number was 1? Because the detection may fail I would recommend try other device ids as well. Sometimes also can help just reboot laptop.

Can be reopened.
