碩士 === 國立交通大學 === 電子工程系 === 88 === There is a result of the difficulties associated with the cost, configuration, and attachment of peripheral devices in the personal computer environment.Because of these shortcoming , many of which led directly to the need for a better solution for attaching peripherals.Numerous solutions exist that might satisfy the requirements of a new method for attaching and accessing peripheral devices. The Universal Serial Bus (USB) creats a solution for attaching PC peripherals that balances performance and cost. Devices attached to USB ports can incorporate additional connections for attaching other USB devices as illustrated in Figure 0-1 . These additional connections are provided via a USB hub. Hubs can be stand-alone devices, or can be integrated into other USB peripherals such as printers or keyboards. In fact, Computer industry is hot for understanding USB knowledge gradually. Hence we make a『Color and Illuminance Analysis System for Front LCD Projector』 automatic test system with USB technique. It follows ANSI standard and the friendly user interface application provides the solution of factory for testing.
