摘　　要：USB接口设备具有即插即用、支持热插拔、传输速度快等优点,因此在嵌入式系统中使用很广泛,但是有很多设备并没有现成的驱动,需要用户自己开发。为解决这一矛盾,通过调用Linux平台下的libusb API函数,对富士通公司的MBF200指纹采集器进行读写操作,说明了开发USB驱动的一般步骤,也可作为其他操作平台USB设备驱动开发的参考。The USB device has the merits of plug-and-play, hot-plugging and high speed transferring, so is widely used in the embedded system. However, many devices have no ready drivers, and it is necessary for users to develop these drivers. In order to solve this problem, by calling the libusb API function of linux operating system, the general method for developing USB drivers is expressed through the reading and writing operations on Fujitsu mbf200 fingerprint sensor, and also the method could act as a reference for driver development of other USB equipments.
