Maybe if someone comes up with the protocol (or some
reference for
the original mouse, like...schematics :oD) I can help in doing
something like a PS-2 converter :)
A rather neat trick I learned for (sometimes) finding schematics of such
stuff is to look at the FCC ID number on the mouse. With that, you can
do a lookup on one of the FCC databases, and you will find things like
manuals, schematics, drawings, etc.
A quick Google search (and a redirect) brought up the search engine:
