PS2 to DB9 adapters only work on mice with "combo" chips in them - PS2 mice
and serial mice are actually quite incompatible but some mice have a
controller chip that is designed to work with such adapters and will detect
them and switch from one to the other. The other fly in the ointment is
that there are actually 2 or 3 different types of PS2 to DB9 mouse adapters
flying around (I can't remember what the differences are but they are
somewhat significant). In general, if a mouse comes with an adapter it's
compatible and if it doesn't it isn't (there are of course exceptions but
I've found them to be pretty rare).
In general, optical (as in non-ball optical) mice aren't able to run with
such adapters, probably because they need more power and the serial port
can't supply that much power (actually serial ports aren't designed to
supply power at all but older ball mice are designed to draw almost no
current so it's OK). Also a lot of newer PS2 mice aren't compatible (most
newer Logitech PS2 mice that shipped with Dell desktops aren't - I tried a
pile of them a while back).

P.S. The same is also sorta true of USB mice - some are combo mice, they
will work with USB or PS2 and others are only USB ... the problem here is
that I've found a fair number of mice that are compatible with both don't
come with adapters ... so it gets even more confusing!

Subject: 70CT and mouse
I bought a PS2 -> DB9 adapter in order to try yo use
a PS2 mouse with my Libretto 70CT, but it don't works.
I have tried with two different PS2 mouses, with the
samd bad result...
I precise that the serial port of the 70CT works fine
with two other real serial mouse I tried
Any idea about this?
