keyboard with USB interface still usable through PS/2 interface

[dimm0k]

Originally I was looking at the Ducky 9008S keyboard, which gives the option to connect via USB or PS/2, but now that it's discontinued with nowhere selling these keyboards I'm looking at its replacement, the Ducky Shine II.  Unfortunately this keyboard is USB only so I was wondering if it's at all usable on computers with only the PS/2 interface.  I would like a keyboard that would allow me to use both in case the need to ever troubleshoot a machine arises and I have no PS/2 keyboards around.

anyone know the answer to this?

You could buy a USB to PS/2 adapter. Should work just fine.

Damn, I was under the assumption that if it stated USB as the interface that converting it to PS/2 with an adapter would not work with keyboards.  So when they say USB and PS/2, they're merely including the necessary adapter for both interfaces?

Usually so. I know my daskeyboard and CM Storm QFR both came with a USB to PS/2 adaptor.

I would assume, yes.

They are including the adapter for you, my Filco says PS2 or USB too, but its USB and came with an adapter

Also, what gave you the assumption that it wouldn't work? Maybe I'm missing something? I was using my das via PS/2 because it allowed for the NKRO.

A passive adapter?  They work in most cases because the keyboard can detect that it's connected via PS/2 and so will talk that protocol.  However there are some notable exceptions, like Unicomp's USB boards which don't do that: strictly USB only.
