usb to ps2 keyboard adapter

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have an asrock b450m pro4 with one ps2 port (coloured purple and green).
I have a usb mouse and usb keyboard.
The goal is to power on with a ps2 keyboard.
I have a purple usb to ps2 adapter that I plugged the usb keyboard into and then connected to the motherboard.

The keyboard lights up (backlight) like it is connected but I can't type.

A. Do I possibly need a splitter cable?
B. Do I possibly need a green ps2->usb adapter (does the colour matter)?
C. Do I possibly need to reconfigure X?

	Apparently some keyboards don't support the PS2 protocol anymore.
