鼠标过滤驱动
我想写一个鼠标的过滤驱动，我的\Driver\mouclass下有四个设置，我刚开始想测试一下，所以所有的dispatch只是简单的把irp下发，中间显示一条debug信息，我用monitor把驱动挂上去后，只检测到一条IRP_MJ_CLOSE的irp流，根本检测不到IRP_MJ_READ流，但我把他挂到keyboard上的时候可以检测到IRP_MJ_READ流，驱动程序应该没问题，难道是鼠标的数据流不是通过IRP_MJ_READ流走的？
求大神出招～～过滤驱动 IRP流鼠标

引用:PNP设备，AddDevice例程调过时会传递一个PhysicalDeviceObject，你只要绑定它就行了（因为你在鼠标类的UpperFilter键下添加了你的驱动，自然会传递Mouclass生成的设备）。
AddDevice例程可能不只被调用一次，你全绑定即可。你测试的时候不要对自己的设备定义设备名，（如果需……

NT式的方法，不用AddDevice，在DriverEntry中绑定设备，调用未公开的API  ObReferencedObjectByName找到mouclass，直接绑定就可以了。至于你说的绑定设备2和3后系统崩溃，，，，，这要看你对IRP的处理了。

不使用upperfilter,附加到mouseclass的
