Re: info on sleep (technical)
 

If this is true, then my machine never ever sleeps, just dozes. Moving my mouse will *always* wake it up. (logitech wireless using logitech drivers)

Re: Re: info on sleep (technical)
 

This is interesting. I have several mice-type items installed, one of which is also a logitech wireless trackball (tho I use USB Overdrive) and, like you, moving the trackball will wake the machine. However, any activity on my Cirque touchpad (other than a button click) doesn't wake my machine. So, perhaps this is something to do with the logitech device rather than your machine is dozing rather than sleeping.

sleep and non-Apple mice
 

The document that I was quoting about not waking when the mouse is moved went on to say: "This is true for machines that have Apple-supplied ADB & USB mice and keyboards or other, conforming mice and keyboards".

So, another interpretation is that your devices are not "conforming", which I guess means that they don't respond properly to the Power Manager protocol mentioned in my posting above. From my reading of the PM documents, this might mean that the whole system would be prevented from going into sleep. Not sure how you can tell though. If it was a laptop, you might be able to tell by looking at the battery consumption with and without the 3rd-party mouse.
