求助！！！驱动卸载时蓝屏 驱动正常启动 并能输出相关信息

[fdgsDZ]

刚学驱动开发 借鉴的是楚狂人的《寒江独钓》系列 结果在写键盘过滤时 卸载功能却无法使用 当时不以为意 然后尝试写一个鼠标过滤设备时 结果还是在驱动卸载这块发生问题
DriverEntry 入口函数
mouDispatchGeneral 通用处理 （打印信息） 正常工作
moBindFilter 绑定过滤设备 应该正常工作 否则 dbgview就不输出信息了
mouUnload 驱动卸载 问题就出这 其调用mouDetach
mouDetach 解除绑定

VOID
mouDetach(IN PDEVICE_OBJECT pDeviceObject)
{
	PC2P_DEV_EXT devExt;
	//BOOLEAN NoRequestsOutstanding = FALSE;
	devExt = (PC2P_DEV_EXT)pDeviceObject->DeviceExtension;

	IoDetachDevice(devExt->TargetDeviceObject);
	devExt->TargetDeviceObject = NULL;
	IoDeleteDevice(pDeviceObject);
	devExt->pFilterDerivceObject = NULL;
	DbgPrint(("Detach Finished\n"));

	return;
}

以前学应用程序开发时 程序崩溃还能使用调试器看下问题出在那 但现在刚学驱动开发 崩溃蓝屏却不知从何入手解决 望前辈们指条明路

[风影-取名字真烦]

其实你不应该这样问问题的，这样子的问题，必须完整看你的代码，还不一定能找到问题
至少应该告诉别人兰屏的兰屏代码，这样才能有针对性的看一看代码，更何况那样不是非常仔细也找不到问题。
我告诉你驱动的调试方法吧，你要是做驱动开发，至少准备好虚拟机内核调试环境，然后在内核出现兰屏问题的时候，调试机的windbg上会有详细的出错原因，甚至出错的代码位置，哪怕不能双机调试，也需要开启windows的内核转储，这样兰屏时候会产生一个兰屏文件，告诉你是什么原因，什么位置出现问题，如果用windbg打开，幸运的是你又有代码，也同样可以定位到出错的代码行，然后你可以去想想为什么出现这个错误了
不好意思，实在不想再建立环境编译你的代码了，你就这样试试看吧

看你写的驱动有没有删除注册表里的信息。
