Possible causes of a self-waking Mac
Authored by: 2stepbay on Aug 01, '07 12:40:12PM

I have a Canon 4400F scanner attached to a Belkin USB 2.0 hub (iMac G5 rev C). If I put the computer to sleep while the scanner is plugged-in to the hub, the system wakes up immediately. Only 2 remedies - plug the scanner directly into the iMac (not practical as the USB cable (6ft) is not long enough (I don't want to buy a 10 ft cable), or unplug the scanner from the Hub. I chose the latter, in fact I keep it unplugged until I need to use it. Doing this allows the computer to sleep as intended.
