And the device works as expected with basic multitouch functionality.

Is this a failure to match IDs from the linux/drivers/hid/hid-ids.h file? I don't have much experience with input drivers.

I wonder if this is because of a kernel version. Ubuntu 18.04 has 4.15, but they seem to require 4.18 based on the readme.

[StrangeNoises]

FWIW it's working on this Ubuntu 18.04... with the Mainline 4.18 kernel. Though I must say I didn't attempt it before upgrading the kernel because of that readme. ;-)

[regis-leray]

did someone succeed to make it work with bluetooth ? i was only able to make it work with USB.
i cannot see the device with bluetoothctl

my bluetooth module works since im able to pair with my phone and apple magic keyboard 2

ubuntu 18.04
kernel 4.18.10

$ lsusb 
Bus 002 Device 003: ID 0a5c:21e8 Broadcom Corp. BCM20702A0 Bluetooth 4.0

[StrangeNoises]

it worked with bluetooth for me, without me having to try, but remember it does require Bluetooth 4.0, so if the machine you're trying it on doesn't have that, it probably won't.

[regis-leray]

@StrangeNoises what kind of information should i look for ?

[StrangeNoises]

I'm afraid I don't know. I belatedly just noticed your lsusb output showing that yours already is a Bluetooth 4.0 interface, so I'm out of ideas (unless, eg: you have two bluetooth interfaces and they're fighting?) It just worked for me so I didn't have to go crawling through the logs.

... and now I've sold the magic trackpad 2 anyway, for Reasons, so I can't try again.

FWIW:

When I used the trackpad in macOS it was mostly on a hackintosh, and there I used -- (plugs it in) -- as it turns out, exactly the same bluetooth adapter as you're using. So there shouldn't be any problem with the device itself being incompatible.

When I used it on this linux laptop - its bluetooth adapter is part of the Qualcomm Atheros wifi/bluetooth combined device, although it just shows up in lsusb as "Foxconn / Hon Hai", not very usefully.

i was dealing with this issue also
#14
i endup by creating /etc/rc.local script which reload the driver

#!/bin/bash
rmmod hid_magicmouse
insmod /lib/modules/`uname -r`/kernel/drivers/hid-magicmouse.ko
exit 0

[regis-leray]

oki i finally found the problem, on the magic trackpad i didnt switch on/off the trackpad. ( i didnt see the small switch on the trackpad)
I also install the latest kernel driver 4.18.13
