Abstract: In an apparatus to be controlled 20 such as a USB-compatible peripheral device connected to a controlling apparatus such as a personal computer, when a specification change is detected such as a change in the apparatus to be controlled 20 itself and a change in the connection situation of an attached device 30 (S201: YES), identification information corresponding to the changed specification is extracted (S205) and the extracted identification information is set as identification information to be transmitted to the controlling apparatus 10 (S206). The identification information having been set is transmitted to the controlling apparatus 10, and the controlling apparatus 10 controls the apparatus to be controlled 20 having the changed specification, on the basis of the identification information.

Abstract: A control system comprising an electronic device equipped with a port, a hub being connectable to multiple external devices and to be connected to the port of the electronic device, and one or more external devices to be connected to the hub, the operation of the external devices connected via the hub being controlled using the electronic device, wherein the electronic device comprises a supplying section for supplying currents to the hub connected to the port and the external devices connected via the hub, and a storage section for storing the magnitude of the total current supplied from the supplying section.

Abstract: Paper (41) on which a first reference image (31) is formed in an image forming section (300), and a correction instrument (1) on which a second reference image (33) is formed, are placed at predetermined positions on an original platen (210). Reference images (31, 33) are read as an image for correction by an image reading section (200). An error in the image reading section (200) is measured based on the second reference image (33) of the correction image. The first reference image (31) of the correction image is used to remove the error in the image reading section (200) from the measured error, resulting in an error in the image forming section (300).
