Apple Magic Mouse too fast (Ubuntu 12.04)

Hi!
I switched to Ubuntu 12.04 from Mac OS. I use the Magic Mouse (multy touch) but it is too "fast" even if i set the preferences for mouse. With the touchpad it's all ok and with the mouse the scrolling of the pages is, instead, too slow!
Any help?
Thank you.

I don't know if there's something specific about this mouse, but you can read this about slowing down your mouse (and other specific Ubuntu mouse configurations)

those instructions are working fine, thanks!

and what about the scrolling speed? is there a way to personalize it?
