The industrial standard of USB is an expansion of the existing architecture of PC. The design of USB mainly follows the following principles: · Easy to use, for expansion of computer peripherals; · Low-cost solution, supporting transmission rate up to 480MB/s; · Full support for real-time data, voice, audio and video; · Flexible protocol, integrating synchronous and asynchronous data transmission; · Compatible with the technology of different devices; · Integrate the structure and system characteristics of different PCs; · Provide a standard interface to widely accept various devices; · Give new functions to PCs so that they can accept many new devices; · USB 2.0 is fully compatible with previous versions of devices; 2.2 Classification Table 2-1 is classified according to the data transmission rate (which USB can achieve). It can be seen that the bit rate of 480MB/s can include high-speed, medium-speed and low-speed situations. In general, high-speed and medium-speed transmission are synchronous, and low-speed data comes from interactive devices. The original intention of USB design is for desktop computers rather than for mobile environments. The software system provides support for various host controllers to ensure the future expansion of USB.
