Debug process
I got myself a new mechanical keyboard (Redragon Horus) after my old one broke
and noticed that the scroll wheel doesn't work as it should. I use KDE Wayland
so I went to the keyboard settings, changed the delay between key repeating and
suddenly it was scrolling properly. This same issue didn't happen on my
previous keyboard (Corsair K70, Red led version) nor does it happen on windows.

When I plug it in I get this message, showing multiple event devices

By using evtest I was able to confirm that Consumer Control is the one in
charge of managing the volume wheel.
Is there anything I can do to fix this problem? The huge delay for the volume
wheel really makes it hard to use and since my old keyboard worked just fine,
I'm sure this must be a problem specific to this model 

STEPS TO REPRODUCE
1. Use the volume wheel present on the keyboard continously

OBSERVED RESULT
Wheel changes the volume, pauses, then after the delay time is set it starts
changing the volume again

EXPECTED RESULT
Wheel changes the volume without delay

SOFTWARE/OS VERSIONS
Linux/KDE Plasma:  Archlinux
KDE Plasma Version:  6.1.5
KDE Frameworks Version: 6.5.0
Qt Version: 6.7.2
