How many wires are necessary to speak the PS/2 protocol? How many pins are there on a USB connector? In front of me right now I have a Microsoft IntelliMouse Explorer USB and PS/2 Compatible mouse, and a Cherry G84-4100PTAUS compact keyboard, which both have USB plugs on their cables and both work with passive USB to PS/2 adapter plugs.
