Abstract
USB(Universal Serial Bus) is the novelly developed external bus currently. With the plug and play and the speed of 12Mbits/s, USB is the most available interface specification applicable to linear CCD data acquisition included the portable PC. The acquisition interface is introduced based on Universal Serial Bus for the linear CCD data acquisition system according the PDIUSBD12 chip of Philips Corp. The design of hardware, device driver and MCU firmware are discussed. The steps of system interface debug are given.
