Converting a PS/2 Keyboard to USB
If you have a older keyboard with a round connector with 4 or 6 pins, known as PS/2, you want to get a true USB converter. You might have seen a lot of small green or purple adapters that are cheap but ultimately don’t work because they are meant to be used with keyboards that already designed already to be a USB peripheral. Thus these adapters only connect the various wires to the USB connector and signal the keyboard to go into USB mode.
So what is actually needed is a more sophisticated adapter with pre-programmed chip to read the signal of the PS/2 keyboard and at the same time act as a USB human interface device (HID) and appear as a keyboard on the computer. Since the HID USB device class is one of the most fundamental devices of any USB aware operating system, no drivers are needed for its basic functions under Window, Linux, or Mac OSX.
Here is a link for a active PS/2 to USB converter.
