OT? PS2<->USB

Possibly on topic due to the year of introduction
of the PS2 serial mouse connection... I recently
picked up a new , fairly low cost mouse (Logitech
optical) without expecting anything but the PS2
connector and lo and behold the thing was native
USB... with a miniscule PS2 adaptor on the end.

My Q is this: is USB somehow an electrical superset
of PS2, IE the adaptor was passive. Or, did they fit
some electronics in that tiny thing?
