*** This bug is a duplicate of bug 777074 *** https://bugs.launchpad.net/bugs/777074 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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/862085 Title: Apple Magic Trackpad (hid-magicmouse) input freezes on 3 or 4 finger touch To manage notifications about this bug go to: https://bugs.launchpad.net/oif/+bug/862085/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Based on what I've read about other people using Apple Magic Trackpad, it seems no one has had as many problems as I have. So a broken dongle sounds likely. If the problem persists after I've tried 1 or 2 new dongles then I might think about calling it a linux bug... :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/862085 Title: Apple Magic Trackpad (hid-magicmouse) input freezes on 3 or 4 finger touch To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/862085/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 862085] Re: Apple Magic Trackpad (hid-magicmouse) input freezes on 3 or 4 finger touch
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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/862085 Title: Apple Magic Trackpad (hid-magicmouse) input freezes on 3 or 4 finger touch To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/862085/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

As mentioned above, I suspect this is a hardware problem. Need to wait for the new bluetooth dongle to be delivered so I can verify. ** Changed in: linux (Ubuntu) Assignee: Chase Douglas (chasedouglas) => Daniel van Vugt (vanvugt) ** Changed in: linux (Ubuntu) Status: Confirmed => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/862085 Title: Apple Magic Trackpad (hid-magicmouse) input freezes on 3 or 4 finger touch To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/862085/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 862085] Re: Apple Magic Trackpad (hid-magicmouse) input freezes on 3 or 4 finger touch
I can almost certainly exclude the hid-magicmouse kernel module now. I removed the module and dumped the raw bluetooth data using 'hcidump -X'. The problem STILL continued. When I used more than 2 fingers, hcidump stuttered and froze. So it seems my problem is either hardware (the cheap bluetooth dongle) or the kernel bluetooth code (unlikely). P.S. Interestingly, I notice the event buffer size used by hid-magicmouse may still not be big enough, even after I find a bluetooth dongle that works. Because hid-magicmouse uses an event buffer size of 60 events, but hcidump showed that when using 3 or more fingers, the bluetooth data packets became bigger than 60 bytes. Not sure if an event is a byte though... #fingers : bluetooth_packet_length 1 : 18 2 : 27 3 : 36-69 4 : 45-87 5 : 54-105 6 : 63-105 7 : 72+ 8 : 81+ 9 : 90+ 10 : 99+ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/862085 Title: Apple Magic Trackpad (hid-magicmouse) input freezes on 3 or 4 finger touch To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/862085/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
