Perhaps you need to install them. I've noticed no changes in this area
between stretch and buster. dpkg -l shows:

I don't use xorg.conf for the mouse (only for coercing video modes on
two simultaneous displays). Instead I slow it down with lines like:
  xinput --set-prop "Logitech M325" "Coordinate Transformation Matrix" ".3 0 0 0 .3 0 0 0 1"
in ~/.xsession.

Actually, ~/.xsession runs ~/bin/xinput-xsession which runs the
appropriate commands for setting all the properties on all my
devices. The advantage is that if you plug in a mouse, then running
xinput-xsession will set it.

Cheers,
David.
