You need an Active, instead of Passive adapter.
ClickKeyboards.comQuestion: My cheap ps/2-USB green or purple adapter is not auto-detected by Windows plug and play and I canít get it to work. Where can I download the drivers?
(typical examples of passive ps/2 to USB adapters that are not true ps/2 to USB signal converters)
Answer: The vast majority of commonly available ps2 to USB converters are simple _passive_ ADAPTERS that simply change the plug shape to match the outlet. These ADAPTERS only function to connect the ps/2 wires to the approximate USB wires. Simple ps/2 to USB adapters do not use specific software drivers.
In general, most users having trouble connecting their keyboard to newer computers are looking for a ps/2 to USB signal CONVERTER. These devices use an integrated circuit (pre-programmed chip) to _actively_ translate the ps/2 keyboard signal and convert it into a USB keyboard signal.
This allows the vintage ps/2 keyboard to be automatically recognized by the operating system as if it were a standard, modern USB keyboard. A well-designed _active_ ps/2 to USB converter will use the built-in operating system drivers for a USB keyboard (for example in Microsoft Windows XP, kbdclass.sys and kbdhid.sys).

This is an ACTIVE adapter ... that works:
