SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. Plug in single mouse
2. Start Wayland Session
3. Check device combobox under System Settings-->Input Devices-->Mouse

OBSERVED RESULT
Shows three options, one of which is my mouse. If options other than the mouse are selected, the sliders/options have no effect. By default, an unknown USB device was selected.

EXPECTED RESULT
Combo box should only contain one option unless more than one mouse is plugged in.

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: 5.17.1.arch1-1
(available in About System)
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.3

ADDITIONAL INFORMATION
I have seen something similar on XFCE in their libinput options screen in the past so I don't know if its actually a KDE-specific issue. I initially made a bug report assuming the sliders simply weren't working (https://bugs.kde.org/show_bug.cgi?id=451296) only to be told (thanks Nate!) that there's a combobox in Wayland when there wasn't in X11. My combo box contains three options: "SONiX USB Device" (this was the default), "Wing Tech Xtrfy M42" (the one that works), and "Wing Tech Xtrfy M42 Keyboard". The mouses' actual name is the Xtrfy M42.

I see this too:  the combo box lists the keyboard as well as the mouse.  Using lshw, the two devices are reported thus:

Can confirm. It almost seems like each physical pointing devices gets two logical ones listed in the combobox.

touchscreen is also detected as mouse, see bug 428520
