本文介绍了USB设备Bulk模式驱动程序的设计。该设计使用FIFO消息队列、信号量机制和定时器中断机制，可在不同的操作系统中实现。文中所用到的程序体系结构对于实现不同USB设备进行Bulk模式通讯是通用的。-This paper introduces the USB device Bulk mode driver design. The design using FIFO message queues, semaphores mechanism and timer interrupt mechanism in different operating systems to achieve. The text of the procedures used in the architecture for the realization of different USB devices Bulk mode of communication is common.
