I also an owner of the 4200f and I searched for information of the Chips  
inside this scanner a while ago. According to this site the chips are:

I didn't find anything about this chip.

chip 3

This scanner uses a Wolfson Electronics WM8196SCDS chip as ADC.

chip 4

MYS 99 507

This is the controller of the scanner motor:

I also made some logfiles with USB-Snoopy with different settings inside  
the scanner software, but I am not a real developer.

Maybe someone could integrate this information on the site I noticed above.
