Hi Gabriel, please avoid sending such html emails to mailing list as it
is hard to read them and also you have a very big chance that email
would be eaten by spam filter or other developers would completely
ignore it...
To debug your problem, can you run smbios-keyboard-ctl tool from the
libsmbios project? https://github.com/dell/libsmbios
We would need output from --info parameter and also from --get-status.
