## Apple Magic Trackpad 2 doesn't work properly on Bluetooth

Hi! I just bought an Apple TrackPad 2 and it's not working properly on Fedora 30 beta, using libinput 1.13.1.

Connected via USB, it works as expected, but over Bluetooth it requires *a lot* of pressure to work. I almost have to click everything to move the pointer!

Anyway, I looked into `/usr/share/libinput/50-system-apple.quirks`

and didn't find the device listed.

I also saw a lot of people say that they had to use the following in a custom quirks file:

```
[Touchpad pressure override]
MatchName=*Magic Trackpad 2
AttrPressureRange=2:0
```

(I haven't tested this yet, as I'll have to reboot and I'm just taking a short break in my workday to file this.)

Ideally, it should work consistently over Bluetooth as it does with USB.

I'm happy to help debug things.

Here's the result of using the touchpad while attached with USB:

```
# sudo libinput measure touchpad-pressure
Using Apple Inc. Magic Trackpad 2: /dev/input/event27
Ready for recording data.
Pressure range used: 30:25
Palm pressure range used: 130
Thumb pressure range used: 253
Place a single finger on the touchpad to measure pressure values.

Sequence 451 pressure: min: 0 max: 89 avg: 26 median: 21 tags: down
Sequence 452 pressure: min: 0 max: 14 avg: 6 median: 7 tags:
Sequence 453 pressure: min: 0 max: 23 avg: 12 median: 16 tags:
Sequence 454 pressure: min: 0 max: 13 avg: 5 median: 8 tags:
Sequence 455 pressure: min: 0 max: 17 avg: 9 median: 14 tags:
```

Everything after `Sequence: no pressure values recorded`

is a click. The first two are actual clicks, the others are taps. Everything above the no pressure values recorded line are just moving the cursor around.

Attempting to use the trackpad over Bluetooth results in the following:

```
Sequence 0 pressure: min: 0 max: 14 avg: 8 median: 8 tags:
Sequence 1 pressure: min: 0 max: 21 avg: 10 median: 10 tags:
Sequence 2 pressure: min: 0 max: 24 avg: 11 median: 10 tags:
Sequence 3 pressure: min: 0 max: 17 avg: 9 median: 10 tags:
Sequence 4 pressure: min: 0 max: 180 avg: 106 median: 123 tags: down palm
Sequence 5 pressure: min: 0 max: 116 avg: 30 median: 11 tags: down
Sequence 6 pressure: min: 0 max: 127 avg: 36 median: 12 tags: down
Sequence 7 pressure: min: 0 max: 25 avg: 14 median: 17 tags:
Sequence 8 pressure: min: 0 max: 31 avg: 16 median: 19 tags: down
```

Everything above the "down palm" line is just touching and moving the cursor around. The rest are clicking and tapping to click. (The last two lines are a double tap.)
