Help needed for: Arduino + optical mouse sensor

Before I start with reverse enginering ...
Has anyone in the forum good pointer for connecting an Arduino to the optical sensor inside optical mouses using the native HW interface of the chip ?
I'm using an A1610 it's a clone of the Avago (HP agilent) ADNS-2610, or any other opti chip for mouse (the other way around , i'll buy the mouse to get the chip).
thx a lot

Search the Arduino playground there are examples and a library.

thx a lot !
