 * Some comments on the structure of send_buffer, image_buffer,
 * and receive_buffer:
 * send_buffer:   The first two bytes are low order and high
 *          byte of the command, followed by at least two
 *          more bytes. The number of sent bytes has to be
 *          even.
 * image_buffer:  This buffer will contain raw data like
 *                jpeg or exif data.
 * receive_buffer:      The first two bytes will be the same as
 *                in send_buffer. This will be checked
 *                here. Then will follow low and high
 *                order byte of the return status. After
 *                that, depending on command and return
 *                status, other bytes will follow.
