摘要：
在嵌入式操作系统上实现USB Host可以使数码相机、新型手机和PDA脱离开PC直接与打印机和扫描仪等设备实现互连。如果能将USB Host内置于数码相机中，就能够将数码相 机中的照片直接输出给USB打印机。本文对USB Host系统软件的协议框架OpenHCI进行了简单剖析。

Abstract:
The DSC, new mobile phone and PDA can connect to a printer or a scanner without using a PC if the USB host system is placed in an embedded system. Tha t is, a DSC has its own USB host, and we can print pictures in a DSC directly through a USB printer. If the USB Host can be built in a DSC, the pictures in it can directly be outputted to a USB printer. This paper discusses OpenHCI, the USB Host system software protocol framework.
Key words: （universal serial bus;open host controller interface, host controller interface, host controller driver）
