Thank you for the reply Dan.
The trackpad works in Windows 11
and has never worked under Debian Bulseye.

Kindest regards
James

Open a terminal and type

lsusb |grep -v hub

Tell us -- exactly -- all the devices that it reports.

That seems likely.

Try:

sudo modprobe i2c-hid

and test to see if it is recognized.

on my Acer Swift 3 it does look like i2c_hid is loaded.

maybe use to look at xinput; if I run xinput on my Acer Swift 3, I get

ELAN1300:00 04F3:3028 Touchpad id=14

in my case the touchpad is already enabled; I disable it by hand as I
cannot tolerate touchpads:

xinput enable 14
