Magic trackpad (05ac:0265) not being identified as a mouse

I've been experiencing some weirdness with the magic trackpad and I have reached the limit of my ability to debug it, so I'd like some help.

I have two computers where the trackpad is identified and is working correctly, and another where it isn't. I can't move the cursor or perform clicks. I've been able to reproduce this in Arch and Debian on all devices.

Here is output from

libinput debug-events

when it working properly

-event13  DEVICE_ADDED                HID 05ac:0265                     seat0 default group5  cap:pg  size 162x115mm tap(dl off) left scroll-nat scroll-2fg-edge click-buttonareas-clickfinger

And here is the same output in the misbehaving computer:

I can verify that data is being sent through "od -x" on the input devices, but I can't move the cursor or perform clicks.

I am running the latest kernel 6.12.6-arch1-1, the latest firmware 20241210.b00a7f7e-1, and the latest libinput 1.27.0-1

There is no difference with the LTS kernel or under X.org, however the trackpad works correctly in Windows.

Any help would be appreciated.
