For the benefit of people who might not be following this thread, are you saying you have a defective Cocolino? Or that the Cocolino does not work on a CD32?
I don't think its defective, just that when combined with the PS2 mice I have tried it draws too much power to function correctly.
It doesn't work on MY CD32.
I'm sure it would probably work on an older ball type mouse, and there may be lower draw optical mice that would work.
But at this point, I get nothing with or without the SX-1 (and I re-tested everything again tonight).
If I am going to use a ball mouse, I might as well use an original Amiga mouse, without the Cocolino.
