+magictrackpad2-dkms
+-------------------
+
+A DKMS module for patching the bcm5947 and hid drivers to support the Apple Magic Trackpad 2.
+
+Tested with Kernel 4.4.0-57-generic on Ubuntu 16.04 LTS.
+
+How to install
+==============
+
+It should be enough to install the package. If it still doesn't work, you may have to copy the kernel modules from
+`/lib/modules/4.4.0-57-generic/updates/dkms/` to `/lib/modules/4.4.0-57-generic/kernel/drivers/hid/`
+
+* http://unix.stackexchange.com/questions/240593/kernel-not-recognizing-new-devices-from-dkms-module
+
+
+How to configure
+================
+
+Configuration happens in `xorg.conf` at 
+`/usr/share/X11/xorg.conf.d/49-synaptics-bcm5974.conf` and with `xinput`.
+
+If your mouse only moves when you press hard, modify the thresholds:
+
+`xinput set-prop "bcm5974" "Synaptics Finger" 0 10 0`
+
+
+How to update
+=============
+
+Install the current kernel sources: `sudo apt-get install linux-source`
+
+The sources are then available at `/usr/src/linux-source-4.4.0/linux-source-4.4.0.tar.bz2`.
+
+Extract following files to `src/bcm5974...`:
+* `/linux-source-4.4.0/drivers/input/mouse/bcm5974.c`
+
+Extract following files to `src/hid...`:
+* `/linux-source-4.4.0/drivers/hid/hid-apple.c`
+* `/linux-source-4.4.0/drivers/hid/hid-core.c`
+* `/linux-source-4.4.0/drivers/hid/hid-debug.c`
+* `/linux-source-4.4.0/drivers/hid/hid-ids.h`
+* `/linux-source-4.4.0/drivers/hid/hid-input.c`
+* `/linux-source-4.4.0/drivers/hid/hidraw.c`
+
+Apply the patches in the same folders.
+
+Build a package with `make`
