Debian Bookworm touchpad not working

Touchpad seems configured, cat /proc/bus/input/devices:

I: Bus=0011 Vendor=0002 Product=000a Version=0063 N: Name="TPPS/2 Elan TrackPoint" P: Phys=isa0060/serio1/input0 S: Sysfs=/devices/platform/i8042/serio1/input/input5 U: Uniq= H: Handlers=mouse0 event4 B: PROP=21 B: EV=7 B: KEY=70000 0 0 0 0 B: REL=3 

cat /usr/share/X11/xorg.conf.d/40-libinput.conf:

Section "InputClass" Identifier "libinput touchpad catchall" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" Driver "libinput" EndSection 

xinput list:

⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ TPPS/2 Elan TrackPoint id=12 [slave pointer (2)] 

but the touchpad isn't functioning. (Both trackpoint and USB mouse work.) System details, lshw includes:
