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

[kurikomoe]

Update 26/02/03

• Replace official driver to imbushuo's driver

---

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. (click to expand) 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

(click to expand) Prepare imbushuo's driver

0. Download the driver from here: imbushuo's driver
1. Decompress the zip to anywhere
2. Enter the folder and right-click the .inf, choose install

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. Install the imbushuo driver like this

Also, you can choose to use `Apple official` driver

Force-install `Apple USB xxx` driver to this device

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

(Optional) 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.

You can use the config tool from this repository to tweak your trackpad（No need to click install driver, just apply is ok)

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.

Hmm, It appears you didn't install the driver from this project at all? (i.e. the settings in the config wouldn't affect things?)

[kurikomoe]

You're right—initially, I couldn't get the driver from this project to work on my A3120, so I wrote the tutorial using the official driver instead. However, I just re-tested everything and managed to get imbushuo's driver working.

I’ve updated the guide accordingly.... Updated (26/02/03)

This is actually incredibly useful, ty. Installing the official drivers with this walkthrough you can get the USB-C trackpad to work via bluetooth.

hi,

I'll post this message in multiple relevant issues in the repo.

So at the beginning of this year, I decided to purchase an EV certificate to properly sign the driver. I was tired of seeing people resorting to the wildest hacks to get the MT2 to work via Bluetooth 😀

I need help testing the driver, especially for hardware I don't have access to, specifically Windows on ARM and the Magic Trackpad 2 USBC.

This signed version supports all the existing features of this project, plus Bluetooth and battery level reading.

Important:

1. Currently, only Windows 11 is supported. Let me know if support for Windows 10 is also desired. NOTE: Windows 10 is not supported out of the box due to issues (not immediately fixable) with the INF validation during signing.

2. The driver can be installed by right-clicking the INF file and selecting "Install". I strongly suggest deleting any previous installed drivers before proceeding: I use "DriverStore Explorer" for that.

Thanks,

Vito
