Review on Logitech Brand PS2 Converter: Monoprice USB Male to PS2 Adapter (102209) by Matthew Bahri

This does not work with the Logitech Deluxe 104 keyboard. The build quality is good and the price <5$ is good. I bought an old PS2 keyboard for troubleshooting. Some keyboards can communicate via USB and PS2. This type works with this adapter. Unfortunately Deluxe 104 SK-720, M/N: Y-SA2 does not work via USB.
