Most probably no, because usually those mice that supported serial had it written on the label. But of course don't count on my answer, it's only a guess.

No, I think that's right. I have four of these (1.0, 1.1A and 1.3A), two different adaptors, and was unable to get any combination to work. The mouse must say on the label that it supports PS/2 and Serial or it won't work.

Not only that, but you need to get the right PS/2 -> Serial converter too (no idea how to know what the "right" one is either). I have two of these Microsoft IntelliMouse that do say "PS/2 and Serial" on them and they both refuse to work with all the converters that I have. 🙁

Thanks for the answer guys. I looked these up on eBay and sure enough, the serial version shows +-12V on the label. Ah well, I guess I’ll keep using my Kensington Mouse in a Box for now. I *know* I’ve got a Logitech Trackman Marble stashed around here, which *does* support serial; I just need to find it!

I guess with passive adapters the mouse itself should have support circuitry for both.
Normally on pc the rs232 port logic high is -12v(or -13v) and logic low is +12v(or+13v) and the ps/2 port uses 5v logic high and 0v for logic low.
Now a universal mouse adapter could be done with a MCU and a max232, or even without the mcu(i don't have the knowledge to do it other way, neither i know any ic made for that).

Yeah, that’s not a bad idea. I’ve already got a working prototype of a USB to Serial mouse converter (using a USB Host IC and MCU; all I’d need is to add a PS/2 port and it would really be universal. (If you added a male to male PS/2 cable it could function in several ways: USB->Serial, USB->PS/2, Serial->PS/2 or PS/2->Serial!)
