If your camera isn't detected by your computer, please try the following:
Try a different USB port on your computer.
Make sure the camera isn't connected to a USB hub or docking station.
If your camera is connected to a USB 3.0 port (usually has a blue plastic insert), try using a USB 2.0 port instead.
Try connecting the camera to a different computer.
NOTE: If your camera isn't detected by a second computer, it may be defective.
