It's funny you should mention that device because it (or at least its 
predecessor, the OmniView) has been a source of non-stop exasperation for me. :)

By that I mean: I've used it regularly to use an ADB mouse and PS/2 keyboard 
with a laptop (going through an iMate into the laptop's USB port).  However, 
when I try to plug in a PS/2 version of that same ADB mouse, (not concurrently) 
the PS/2 mouse behaves from the get-go as though I'm holding down the mouse 
button when I haven't touched it.  Yes, it could theoretically be behaving that 
way because of a bad port on the converter, but I can't help but think that if 
the port were bad, it wouldn't support mouse movement, which it *does* support 
just fine.

It's the mouse button signaling alone that's screwed up. Which renders the 
mouse unusable, as since the mouse button is (apparently) signaling that it's 
being held down, you end up selecting everything as you move the cursor around 
the desktop.

Is there some blindingly obvious solution to this problem that I'm missing? 
Because I can't tell you how frustrating it is not to be able to use a PS/2 
mouse with a device that has a port for a PS/2 mouse and purports to support 
their use with a Macintosh just fine.  Is it that final USB connection to the 
laptop that messes up the button signaling of the PS/2 mouse?

Thank you for that link.  It's too bad GeeThree doesn't produce that device any 
longer, as it would allow me to determine if the problem I have lies solely 
with the converter, or with the PS/2 mouse itself.

Yes, getting back to the original subject, I may be left with trying to do 
something along those lines.
