I can't download pictures to my computer error message says cannot detect camera My computer used to detect my camera and allow me to download pictures but it all of a sudden stopped and now I keep getting cannot detect camera message.

Need a faster answer?
I just experienced this problem and went round in circles for a few hours before stumbling on the solution. My camera, a Sony Cybershot, has 4 USB Connect modes in the Setup menu: PictBridge, PTP, Mass Storage, and Auto. The only mode that would work to bring up the Camera Wizard screen on an XP computer was PTP. Once I changed the setting from Auto to PTP, the camera was recognized and able to connect to the computer. Somehow this setting had got changed to Auto or Mass Storage and that evidently causes a problem such that XP does not recognize the camera.
