Comment 6 for bug 578520

I have installed the multitouch-kernel package and it worke well for me until May-25.
On 25-May I have used the magic mouse normally, but today it isn't working well and the mouse seems to be recognized as a "touchpad" and I can move the cursor by touching the surface only. Yesterday everything was right, the mouse worke properly and the multitouch surface worked like the "mouse wheel".

On 25-May, the following lines din't appear on my syslog file:

May 26 06:32:04 e4300 kernel: [ 68.209883] Bluetooth: HIDP (Human Interface Emulation) ver 1.2~multitouch
May 26 06:37:25 e4300 kernel: [ 32.909262] Bluetooth: HIDP (Human Interface Emulation) ver 1.2~multitouch

May 26 07:22:02 e4300 kernel: [ 143.699573] Bluetooth: HIDP (Human Interface Emulation) ver 1.2~multitouch

And below are the lines that I think are related to magicmouse (25 and 26 - May):

I don't know if it helps, but it seems that on 25-May (when the line Bluetooth: HIDP (Human Interface Emulation) ver 1.2~multitouch doesn't appear on my syslog) the mouse worked well. On 26-May, it isn't working.

I'm not an expert on hardware issues but maybe this information can help someone to figure out a solution.

Regards,
Rodrigo.
