[Tutorial] Magic Trackpad typec (A3120) USB+Bluetooth Setup

[kurikomoe]

After some trial and error, I finally got my A3120 Magic Trackpad working on Windows 11.
Here’s my procedure (I uninstalled all the drivers and redid everything from scratch).

Perquisites

Download Apple official trackpad drivers from here

Steps

0. Uninstall any drivers associated with trackpad (optional)

/* You can skip this step if you haven’t force-installed any drivers for the Apple Trackpad. */

First open powershell/cmd in admin mode. (you can find one in win+x)

> pnputil /enum-drivers

Find apple related ouputs:

Find wang related outputs, if you have installed any drivers from https://github.com/imbushuo/mac-precision-touchpad

# Run the uninstall commands, and replace oemXXX.inf with the one you found.
# For me, it's oem231.inf  oem168.inf  oem230.inf
> pnputil /uninstall /delete-driver oemXXX.inf

Now, re-plug the magic trackpad.

USB Setup

1. Connect your trackpad via type-c, then open device manager.
   The trackpad should work like a buggy trackpad (can only move cursor and left click)

2. Select View-> devices by container

3. Find Magic Trackpad, You can easily find it since it's not working XD

4. Ignore the alert mark, select the USB Input Device with USB\VID_05AC&PID_0324&REV_0410&MI_01

Note

It may vary, so here's another way to find out the correct USB Input Device
Just disable each USB Input Device one by one. After you disable one, test whether the trackpad still works.

5. Force-install Apple USB driver to this device

Installing the driver may take about 30 seconds, so please be patient.

Confirm and reboot (it should work without rebooting — at least on my laptop).
Now the Magic Trackpad should work over USB as a Precision Touchpad.

Bluetooth Setup

0. Disconnect the USB
1. Pair the trackpad via Bluetooth
2. Open Device Manager, Follow Step.2 in USB Step
3. Now you will see another trackpad like this, this time only one USB Input Device

4. Just like step.5 in USB Step, replace the driver with ApplePrecisionTrackpadBluetooth

Now the trackpad should work under bluetooth mode

Bonus

I expected the trackpad’s polling rate to differ between USB mode and Bluetooth mode, but there’s actually no difference on my A3120.
