I've had ELPH100HS for 2 years. Up until now, everytime I transferred pictures to my computer, a camera icon would appear when I connected the camera via USB to the PCU. But, recently, the icon is missing, but I hear the bleep (connecting sound) I always have. However, I am unable to transfer pictures to the computer. The message that keeps popping up is "support device not found." I can't find my discs or my manufacturer's book that came with the camera. What should I do? Thanks. RAY
