Canon Powershot A610 Webcam My Canon Powershot A610 Won't Connect?

My Canon powershot A610 won't connect? - canon powershot a610 webcam

I'm trying is to use a Powershot A610 as a webcam, not recognized when I use the PC connection, the cable is good, I've been tested, so it is a USB port. I have tried to find drivers online, but it has nothing to Windows XP. Each help'll be appreciated! :)
