Is it possible to disable the "ability" of a USB device to wake a Mac from sleep? I'm asking because I always tiptoe around my Mac, making sure not to breathe on the mouse, touch the printer power button, take my iPod out of the port, etc. I'd like to only be able to wake my Mac via the keyboard but it seems there's nothing out there on the Internet that says I can do what I want to. I'm asking because this is similar to the Mac start-up chime where everyone said it couldn't be silenced but there are in fact a few ways to silence that. Hoping it's also possible to stop USB devices from waking Mac from sleep (selectively). Thanks.
