Re: Twiddler2 PS/2 question

From Wear-Hard Mailing list Archive (WH) Maintained by R. Paul McCarty

Yup, they really are passive, while there are 6 pins on the PS/2
connector, there are 4 connnectors on USB. The keyboard or mouse has
both PS/2 signalling and USB signalling coming out of the device. When
it is plugged in, the keyboard or mouse itself figures out whether it
is plugged into USB or PS/2 an activates the correct signalling
method.

So, NO, I would say the Twiddler PS/2 does NOT work with a passive
adapter, because if it did, they would have included one in the box.
