I have some USB/ps2 capable mouse sensor from a USB mouse.


I want to use the sensor in PS2 mode and the datasheet says there is an internal switch for that and I also want to get that image data from the sensors.


But the problem is that the datasheet does not provide details on the internal switches and registers and how to write to register.


Is there any way I can find/detect those switches and register automatically and then proceed.


P.S I am a  noob.
