Hi, i've been seeing the same issue with a magic mouse and the
"Cambridge Silicon Radio" bluetooth dongle on one of my pc's on gentoo
running kernel versions 3.12.x as well as on my main desktop running
windows 7 64 bit with an asus builtin motherboard bluetooth adapter of
the make from atheros "ar3011" as mentioned by Mr Khimani. Seeing same
behavior on both, works great with 1 or 2 finger touch, but locks up
with 3 or more touches on the touch surface of the mouse. Reading this
bug report i now understand why it works normally with the microsoft
driver on windows, as its not even registering the touches (more than
1). The mouse however works both on gentoo and windows on two other
laptops with a broadcomm bluetooth adapter (on each). So its in fact
either the dongle itself or the firmware/drivers t hat are bugged for
the bt adapter

Title:
Apple Magic Trackpad (hid-magicmouse) input freezes on 3 or 4 finger
touch
Status in Open Input Framework:
Invalid
Status in Unity:
Invalid
Status in “linux” package in Ubuntu:
In Progress
Status in “unity” package in Ubuntu:
Invalid
Bug description:
Update: The cause has been traced down to either a kernel or hardware
issue as per comment #4.
TEST CASE:
Test case without X or Unity:
1. Pair the trackpad using hcitool/hidd utilities.
2. Run: evtest /dev/input/whatever
You will see lots of input events for 1 or 2 finger touches. However the
evtest event stream freezes when 3 or more fingers are touched.
Test case in Unity:
Touch 3 fingers: After a second or two (?!) the grab handles appear but the
trackpad goes dead. Only my mouse continues to work. The trackpad comes back to
life a while after the grab handles vanish, and I've moved the pointer with the
mouse.
Touch 4 fingers: Trackpad goes dead again. Takes a while before it starts
responding again. This also triggers bug 859069.
I can reproduce the above bugs in Ubuntu 11.04 and 11.10 beta 2 (live).
