Daniel,

Great job digging into this! It's really interesting that you see the
same issues when dumping from the bluetooth stack directly.

The evdev event buffer is after the bluetooth stack has handed events
off to the hid-magicmouse. Also, the input event buffer is set to 60
events, not 60 bytes. Based on these two observations, I agree with your
thoughts that it is either a bluetooth hardware/driver bug or a bug in
the bluetooth stack.

I would suggest posting your findings to the linux-bluetooth mailing
list: http://vger.kernel.org/vger-lists.html#linux-bluetooth. That's
where the core bluetooth developers hang out. They may have seen the
issue before and know how to fix it, or they may know off the top of
their head where to look in the stack.
