Abstract: A system for enhancing universal serial bus (USB) applications comprises an upstream processor, a downstream processor and a main controller. The upstream processor accepts standard USB signals from a USB host and independently provides responses required by USB specification within the required time frame. The upstream processor also contains storage for descriptors for a device associated with this upstream processor. The main controller obtains the descriptors by commanding the downstream processor, and passes them to the upstream processor. The downstream processor connectable to USB-compliant devices accepts the USB signals from the USB-compliant devices and provides responses required by USB specification within the required time frame. The main controller interconnects the upstream and downstream processors, and provides timing independence between upstream and downstream timing. The main controller also commands the downstream processor to obtain device descriptors independent of the USB host.

Abstract: In an input device, a controller for controlling an input portion and acquiring data is connected to a bus. The bus can be connected with an external expansion device via an expansion connector. The connection of the bus from the expansion connector to the controller is switched on and off by a switcher. Data acquired from a sensor having a function equivalent to that of the external expansion device is transmitted to the controller via the bus by a sensor controller which is connected to each of a side of the controller and a side of the expansion connector of the bus without interposing the switcher. The sensor controller switches the connection of the switcher off when an access to itself is made from the controller.
