[Bug 1392770] [NEW] Three fingered tap kills apple touchpad input

 

Public bug reported:

I have the apple magic trackpad paired with my Ubuntu 14.04 desktop. It
works fine until a 3 fingered tap (usually accidental), when it stops
responding to input at all. After several minutes it starts functioning
again, usually quicker if I execute "sudo hciconfig hci0 reset".

The problem is also described here (by someone else):
