Logitech Marbleマウス - KDE

私は新しいDebian 12システム（WaylandではなくX11のKDE）とLogitech Marbleマウスを持っています。右側の小さなボタンとボールを使ってスクロールできるように設定するのに役立ちます。https://wiki.archlinux.org/title/Logitech_Marble_Mouse

次のような古くて安定した構成は何の効果もないようです。

cat /etc/X11/xorg.conf.d/10-evdev.conf

#
#       The Logitech Marble Mouse buttons are mapped [A-D] from left to right: 
#       A (large); B (small) |  C (small); D (large). 
#
#       Preferred options for right-handed usage:
#       A = normal click [1]  
#       B = middle-click [2] 
#       C = middle-click [2]
#       D = right-click [3]
#       Hold button B while rolling trackball to emulate wheel-scrolling. 
#       Pressing both large buttons simultaneously (b) produces a "back" action.

# Ids for actions.
# 1     Large button left       normal click
#  2    Both large buttons      middle-click  †
#  3    Large button right      right-click
#  4    (not a button)  -
#  5    (not a button)  -
#  6    (not a button)  -
#  7    (not a button)  -
#  8    Small button left       browser back
#  9    Small button right      browser forward
