These are passive adapters that simply change the plug shape to match the outlet. (They connect the PS/2 wires to the approximate USB wires.) They do not have a chip with software drivers to translate the PS/2 keyboard signal to a USB keyboard signal. They will work only for keyboards with a PS/2 plug that can also give a USB signal. These adapters may work with a PS/2 mouse though.
Buy 1 for R24.
