3. Only the bottom three buttons of a Logitech G604 mouse are recognised, not the top three.

It's likely the mouse exposes them as keyboard buttons (therefore masquerading as being both a mouse and a keyboard), rather than mouse buttons.

Is there any further information I could give to help? Any kind of tool I can run to output some mouse information? if this cannot be fixed on the Plasma side, that's totally fine, but if there is any further information I can give I am more than happy to help provide it.

I noticed that on my mouse now I cannot configure the side buttons in Plasma 6.4.0 and now 6.4.1. Never had a issue with it before.

Hello!

I had the same problem reported in this topic.

I use Fedora and I followed these steps:

1- I downloaded the latest Fedora ISO dated 03/07/2025;
2- I put the ISO on a Pen-drive with Ventoy;
3- I started the ISO when the notebook booted;
4- Fedora started normally and Plasma recognized the side buttons of my mouse (generic mouse) normally;
5- I installed Fedora on the notebook;
6- I restarted the notebook and started the system normally from the local disk. At that moment, Plasma still recognized the side buttons of my mouse;
7- I updated the system to the latest version (data below);
8- From that moment on, Plasma stopped recognizing the side buttons of my mouse.
