Notebook keyboard does not work with Manjaro

Hi,

I installed Manjaro/KDE on a new Notebook (Medion Akoya S17405).
The keyboard now gives no response.
In Grub menu or in BIOS it works fine. If the system is startet only some special key work. I can switch the key backlight on an off, adjust the screen brightness and screen on/off. Thats all. Every other key gives no response.

I googled a lot about it but cant find a working solution.
I hope you can give me a hint.

Here some data:

Select the device event number [0-22]:

For me it looks like there is no keyboard detected!?!? The Logitech is a USB keyboard.
The brightness keys react with event3.
Maybe there is someting wrong with the ELAN? There is no mouse installed .

When pasting terminal output, highlight it and use the Preformatted text </> button, not the Quote " button.

Alternatively, add three backticks ` above and below the text:

```

Please edit your post accordingly.

Seems so, you can clarify through xinput list.

A touchpad may be registered as both touchpad and mouse, nothing wrong with that.

Yep, definitely not detected. As for how, we don’t know yet. Maybe check grep -i keyboard /var/log/Xorg.0.log? There could be some clue there.

Is it normal the wecbam is detected as keyboard?
