PS2 Keyboard not detected

0nepiece used Ask the Experts™
Hi everyone,
  I've connected my ps2 keyboard via ps2 to usb port adapter into my acer aspire one usb port, but it was not detected. The green leds did lit up once I plugged in the adapter in the usb port, so it means that there's no problem with the cord, right?  I've downloaded this "Launch Manager" from cnet but I'm still figuring out how to use this. I'm I doing things right? Please help me out. Thanks in advance.

Wrong adapter.

You may have the cheap passive type adapter instead of the proper converter.


Hi dbrunton,

  Thank you for your reply. I've read your reference, so I think I'm not using the converter type since a pre-programmed chip wouldn't fit in the p2 connector cylinder . Well I was hoping you could I identify what's the real use of this cord, cause I just found it in my stack of usb cords :D. Thanks dbrunton.

This cable looks like it came from a POS system (point of sale system). I t is used to provide power and a connection to the msr and older pinpads to the POS terminal.

I'm having trouble identifying the connectors at the NON-USB ends in your graphic.

They don't look like PS2 connectors or I am looking at it wrongly?
Robert RComputer Service Technician
Yes the one end is a ps2 connector on the far left is a power connector to power on the pinpad power is received from the usb connetor when you connect to the usb port of the computer.

Agree with web_tracker.  To me, this looks like an inline power tap intended to provide +5V power for some small external device.  Some webcams come with adapters such as this; it can pull +5 from either a PS/2 keyboard connection or a USB socket.  As to what device it was originally supplied with, I've no idea.  But it's not likely to be a PS/2 to USB adapter, all of which I've seen are small green inline units.


Thanks for your inputs! I greatly appreciate them :D Now I know. And sorry I took long to grade. :D Thanks again.
