Adapter PS2 to USB keyboard is OK - isn't it?

  Diemmess 16:10 19 Mar 2013

An ageing keyboard using the PS2 connection, has some unreliable keys and must be replaced anyway. O.S. is XP

The majority of keyboards offered are USB

What snags if any are there in attaching a new keyboard using its USB with an adapter to the PS2 socket?

It has been a few years since I used an adapter as it has some years since I used a PS2 connection but my mechanical keyboard (Ducky Shine 11 )came with an PS2/USB adapter as USB does not support Key Rollover.

Explanation here: Key Rollover (#KRO & NKRO) NKRO is when you can press as many keys as you want at the same time, and all of them go through. This is similar to what some 'gaming keyboards' incorrectly market as "anti-ghosting", even though Logitech and Razer only apply it to the WASD cluster. Note that right now only PS/2 keyboards can exhibit full n-key rollover; though Microsoft and Ducky are just two companies who have already looked at designing NKRO over USB.

So I suspect there are no 'snags' connecting your keyboard using the adapter.

I'm using these adapters on mouse and keyboard with no problems.

Thanks for interesting replies.

I apologise for stirring this when the answer should have been obvious to me had I engaged brain first!

You can specify a PS2 keyboard but many USB keyboards come with adapters anyway. As long as you have a spare USB socket the a USB one will be fine.

I have been using PS2 adapters for some time because of a shortage of USB slots. A recently purchased mouse refuses to operate through the PS2 but is fine on USB for some reason. make sure your keyboard is suitable for an adapter.
