Fortunately there was an old USB laser optical mouse lying in my drawer.
The scroll-wheel is broken, but since KitKat doesn't have one it's not a problem :-)
The PCB was too large to fit into the enclosure and the switches needed to be repositioned.

Rearming KitKat with a frickin' laser (and USB)
The kids returned from a Children's day festival with a bag of more or less worthless trinkets, among them a lovely KitKat promotional ball mouse. Its fatal handicap is the connector - the last time I had a PS/2 in my machine was a decade ago ...
I contemplated building a PS/2-USB interface with an Arduino, but lacked the 3.6V Zeners used in the circuit I found on the intertubes.
Fortunately there was an old USB laser optical mouse lying in my drawer.
I decided to transplant its innards to KitKat.

The PCB was too large to fit into the enclosure and the switches needed to be repositioned.
Cut, resolder, rewire, fasten with hot glue,
et voilà - a USB KitKat laser mouse!
