Subject: Fwd: keyboard not working Asus Expertbook B2502CVA

Hi,

I notice a bug report on Bugzilla [1]. Quoting from it:

> Hi everynoe,
> 
> Component: Asus Expertbook B2502CVA
> OS: Ubuntu 22.04.2 LTS
> 
> I am having a keyboard issue after installing Ubuntu 22.04 LTS on my Asus ExpertBook B2502CVA, I discovered that the built-in keyboard is not functioning. The keyboard works perfectly under Windows 11, which leads me to reasonably suspect a hardware compatibility issue with Linux. 
> 
> I found that BUG 216158, Bug 216864, Bug 217323 has similarities to my situation, attachment is my dmesg.

See Bugzilla for the full thread and attached logs (dmesg, dmidecode,
lsmod, and xinput outputs).

AFAIK, this looks like hardware support for Asus B2502CVA is missing
(maybe the quirk?). The reporter also confirms that this bug is
also present on current mainline kernel.

Thanks.
