An image sensing device includes an image sensing unit, an interface unit, a control endpoint, an isochronous endpoint, a bulk endpoint, an interrupt endpoint, and an interface unit controller. The image sensing unit senses a moving image and a still image. The interface unit is connected to an external device. The control endpoint receives from the external device a command requesting transfer of the still image. The isochronous endpoint transfers the moving image sensed by the image sensing unit to the external device. The bulk endpoint transfers the still image sensed by the image sensing unit to the external device. The interrupt endpoint transfers error information. The error information includes information indicating that an error has occurred during sensing of the still image. The interface unit controller transfers the error information to the external device through the interrupt endpoint in response to the occurrence of the error.
