Add Recognition of Apple Magic Mouse 2 to Ubuntu Trusty

• The kernel module produced by these tools will not provide anything that the default Ubuntu mouse driver already provides.
• The MM2 will still only function as a basic 2-button mouse! ... but it WILL be using the hid_magicmouse kernel module.
• The install script is only tested on Ubuntu Trusty (14.04) LTS. It may work on other relases/distros with appropriate changes. YMMV
• The script is provided as-is with no guarantee whatsoever.

These tools are intended for use by developers familiar with kernel module development and tinkerers who wish to experiment with the Linux hid_magicmouse kernel module on Ubuntu Trusty. If you are comfortable writing BASH scripts and are familiar with the process for compiling and debugging custom kernels and modules, please read on. Otherwise, STOP HERE, STOP NOW.

In order for the system to recognise the Apple Magic Mouse 2 as a Magic device, we need to ...

1. Pair the Magic Mouse to the system using the usual Bluetooth methods.
2. Add the new vendor_id and device_id to the modprobe config and the udev hwdb.
3. Patch the current hid_magicmouse kernel module and hid-ids header to recognise the new vendor and device ids.
4. Load (or reload) the hid_magicmouse module after the update.

After step 1, run "./magicmouse2_build.sh" to perform steps 2 through 4.

Uninstall: Read the "magicmouse2_build.sh" script and reverse the steps performed. TL&DR: Restore the contents of the /lib/modules/${KERNEL_VER}/kernel/drivers/hid" dir from the backup. Remove /etc/udev/hwdb.d/21-apple-magicmouse-vendor-model.hwdb

ToDo:

Figure out how to convince the mouse to enable touch features.

Notes:

Device aliases for original Magic Mouse and Trackpad:-

Magic Trackpad: alias hid:b0005g*v000005ACp0000030E hid_magicmouse

Magic Mouse: alias hid:b0005g*v000005ACp0000030D hid_magicmouse

Magic Mouse 2: alias hid:b0005g*v0000004Cp00000269 hid_magicmouse
