US 2006/0069841 A1 · Method and system for data transmission and control based on USB

Abstract

The present invention concerns a method and a system for data transmission and control based on Universal Serial Bus (USB). The system comprises a USB Master device and a USB Slave device. The USB Master device comprises a USB Master processor and a Data Storage connected to the USB Master processor. The Slave device comprises a USB Slave processor and a Data Consumer connected to the USB Slave processor. The USB Master processor is coupled with the USB Slave processor via a USB cable. The USB Master processor accepts requests from the USB Slave processor and reads data in the Data Storage connected to it, and then the data is sent to the USB Slave processor via the USB cable, and the USB Slave processor processes the data and transfers them to the Data Consumer for use.
