AT91RM9200的USB host和USB device的代码ADS1.2. USB-Device测试程序: 因为程序运行在SDRAM中，所以要先初始化SDRAM（可用basic boot程序初始，之后不能复位或断电），再运行此程序，程序运行后连接USB端口，计算机会提示检测到新硬件，安装硬件驱动程序atmusb6119.inf 后计算机会把USB端口虚拟为一个串行的端口使用-AT91RM9200 the USB host and USB device code ADS1.2.USB-Device test procedure: Because the procedure is running in SDRAM, and so we have to initialize SDRAM (available for the initial basic boot procedure, followed by Can not reset or power off), then Run this program, the program to run after connecting USB port, the computer will be prompted to detect the new hardware, installing hardware drivers after the computer will atmusb6119.inf virtual USB port to a serial port to use
