USB主机方式的应用可以参考CH375的资料，与计算机连接的USB设备方式（或自己做U盘）可以参考CH372 的资料。如果是读写U盘并且用量较少或者是系统集成，关心快速入门并且简单易用，那么可以参考半成 -USB host mode the application can reference CH375 information, and computer-connected USB devices (or their own to do U disk) can refer to the information CH372. If it is to read and write U disk and the amount of less or systems integration, care and easy-to-use Quick Start, it can refer to semifinished
