linux系统下3G模块USB串口驱动程序源代码最新版本，附pdf文档档。3G的USB modem都用得着，有了这个就可以在linux下使用了。 (3G module USB serial port driver in the linux system source code version of the attached pdf document file. 3G USB modem need it, with this you can use under linux.)

驱动开发的一些简介，帮助大家理解什么是驱动，什么是DDK(Some of us driven development to help people understand what is driving what is DDK)

枚举驱动列表，获取驱动的设备句柄 这是Win7上常用的获取设备句柄的方法。 我在原代码的基础上，添加了SetupDiEnumDeviceInterfaces 来获取驱动的详细信息。(SetupDiEnumDeviceInterfaces SetupDiGetClassDevs SetupDiEnumDeviceInterfaces)

NDIS 6中间层过滤驱动实现源代码，实现功能为网速限制，实现算法为漏桶算法。(NDIS 6 middle layer filter driver source code, to achieve the function of the speed limit, for the leaky bucket algorithm algorithm.)

说明：  基于VC环境下的光驱驱动程序，可实现对光驱的弹出和关闭操作。(VC environment based on CD-ROM driver can be realized on the drive pop-up and shut down operations.)

FT232RL 驱动程序，支持win7 64位使用。(Use FT232RL drivers, support Windows 7 64- bit.)

在linux环境下编写一个控制台应用程序，程序中有一个共享的整型变量shared_var，初始值为0；创建一个线程并使其立即与主线程并发执行。新创建的线程与主线程均不断地循环，并输出shared_var 的值。主线程在循环中不断地对shared_var 进行加1操作，即每次循环shared_var 被加1；而新创建的线程则不断地对shared_var 进行减1 操作，即每次循环shared_var 被减1。观察程序运行的结果，并对你看到的现象进行解释。(Written in the linux environment a console application, the program has a shared integer variable shared_var, the initial value of 0 create A thread and make it run concurrently with the main thread immediately. The newly created thread and main thread are constantly circulating, and the output shared_var Value. The main thread in a loop constantly on shared_var are incremented, that is plus 1 for each cycle shared_var and the new line created Process is constantly on the shared_var decremented, that is, each cycle shared_var is decreased by 1. Observe the results of running the program, and you To explain the phenomenon seen.)
