Abstract
When a digital camera capable of being set to implement the function of a card reader or camera is connected to a computer via a USB, the computer is notified of the function to which the camera has been set. When the computer and the digital camera are connected by the USB, a device request is transmitted from the computer to the digital camera. Upon receiving the device request, the digital camera determines whether its operation at the time of the USB connection is that of a card reader or PC camera. Information indicating the result of the determination is incorporated in a device descriptor, which the digital camera then transmits to the computer. On the basis of the device descriptor, the computer detects the type of operation to which the digital camera has been set. The driver that supports this operation is loaded and the relevant commands are transmitted from the computer to the digital camera.
