It's possible that the PS/2 plug specification doesn't supply the necessary level of power for the LED and/or laser circuitry required for optical mice, thus making PS/2+Optical impossible. On the other hand, something in my brain is tickling me, telling me that once I used to have a PS/2 optical mouse.

Anyone know for sure if such a beast ever existed? I'm curious.


I've never seen a PS/2 optical mouse, BUT I seem to remember that at work we used for years USB optical mice + USB to PS/2 adapter, connected to a PS/2 port. So, IIRC, PS/2 would provide needed power.
