dell quiet keys - active or passive converter

[QuincyJones]

I still haven't got around to doing anything with this - and I can't find my green converter, so do I need to buy an active or passive PS/2 to USB converter for an earlier Dell QuietKey? The RT7D5 earlier version.

The cheap passive one has worked for me.

yeah, probably.

I think the passive one is working - kind of.. When I connect, the LEDs power on, but only the num lock key works. https://geekhack.org/index.php?topic=82707.0

Did you test it via PS/2 to ensure that the keyboard is actually working?

Finally got to test it on an old pc with interesting results. It appears the keys seem to work after a quick test, but some of the keys result in two characters appearing - e.g. "c" press = "c.", "r" press = "r." and "3" numeric press = "3,". So I'm guessing that means there's cross talk somewhere?
