嵌入式Linux终端设备中通过USB同步数据的设计与实现

Design and Implementation for Synchronization over USB in Terminal Based on Embedded Linux

介绍了 USB的广泛应用以及在嵌入式 Linux系统中增加 USB支持的几种理论方法 ,集中在 ethernet overUSB,然后详细介绍了基于 PXA2 5 5嵌入式 linux系统中通过 USB进行数据同步的实现 ,电路设计 ,驱动中具体进行数据传输的实现 。

The paper describes an applications of USB. Several methods of supporting USB in embedded Linux system are introduced, which focus on ethernet over USB. The main contents of this paper are the design and implementation for synchronization over USB in Linux based on PXA255, including the hardware circuit, transmission of data, resolution for hotplug and the configuration over host PC.
