Do you have an updated version of your patch that applies to
git-current? I will give your patch another try then.

OK, indeed it never autosuspends... I guess this is this due to the
keyboard and the mice being on the same usb port and as the kbd part
does not support autosuspend it never suspends?!

Well reaching this line the touchpad is idling (hasn't been touched+no
button was pressed) - I somehow wanted to force it to suspend in this
case.

perfectly + reliably the way it is.
