A microcontroller based intelligent instrumentation extended USB interface. Introduced a USB interface chip SL811 HS structure and performance, and USB interface, hardware schematics, detailed analysis of the USB interface driver of the design method and FAT16 file system structure. Transmission using SCSI command set, by BULK-IN and BULK-OUT endpoint achieved between the host and U disk devices for data communications. Experiment and application results show that the scheme is easy to control, transmission speed, stable and reliable data storage.
