I just got a Canon Powershot S410, but iPhoto doesn't seem to recognize when I plug it in via usb. Ideas? Specific Questions: 1) Do I need to turn the camera on manually? Or can I plug in a powered down camera and have it turn on automatically? (Obviously, I've tried both, but if there's a definitive answer out there it'd be nice.) 2) I think it might be the USB cable because my computer at work didn't recognize it either. At the time, I just assumed it was random Win98 flakiness and I was too busy to fix it. Now I'm not so sure. Is there any way to verify the integrity of a new cable? help!
