Apple Magic Mouse scrolling in Ubuntu 9.10

"So far no, the magic mouse does not have a standard way to provide scrolling information. As best as I can discover, the pairing process checks the ""PNP Information"" profile to find the Manufacturer and Product IDs (to match Apple/Magic Mouse) then sends some HID Feature reports to enable the special features of the touch surface and set the device name. Then, the mouse sends reports of the finger touch data and I don't know what they mean. Going from the HID descriptor, it may be that there is an array of sensors on the surface of the device that just show finger positions.

Sorry I don't have a mouse or a mac (or ubuntu :) so I can't provide any more information about this and am unable to experiment at this time.

I suspect the driver will need to interpret the sensor array data manually for single and multi-touch and generate its own 'scroll' and 'pan' events, along with middle-click if required and any other kind of swipes.."
