I want to know the answer to the following question:
What performs bidirectional data translation between two standards?
All the background I'm provided with is that "For mice and keyboards with dual-protocol support, an adaptor that contains no logic circuitry may be used: the hardware in the USB keyboard or mouse is designed to detect whether it is connected to a USB or PS/2 port, and communicate using the appropriate protocol.". Is that enough to answer the question?
