PnP filter driver 到底问题出在那里 ??

最近在做PnP filter driver,直接用Microsoft的code
http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q262305
加上下面的 inf file,从新增硬件手动安装,但不成功!
发现在case IRP_MN_START_DEVICE: 里的IoCallDriver反回Status = c000009a
(Insufficient system resources exist to complete the API.)
到底问题出在那里 ??

应该是驱动问题吧，inf能有问题？

用DS的Monitor加载有问题吗？

先加分!! 顶一下 !

    deviceExtension->NextLowerDriver = IoAttachDeviceToDeviceStack (deviceObject, PhysicalDeviceObject);
.
.
.
status = IoCallDriver(deviceExtension->NextLowerDriver, Irp);

NextLowerDriver是从IoAttachDeviceToDeviceStack里得来的
IoCallDriver(deviceExtension->NextLowerDriver, Irp);
返回Error是C000009A

此程序的源代码在 Windows 2000 and Windows XP DDKs under <DDK root>\Src\General\Toaster\Filter\.
在运行这段代码之前,请先编译toaster目录下的bus,func,toastmon.
另外,你的inf文件写的也不正确,请参照ddk中toaster下的inf.
toaster是一组十分好的示例代码,建议好好研究.

怪了,路径符号打不上去.
filter sample 在toaster目录下,搜索一下.

机里有两串口,Serial0和Serial1.
但deviceExtension->NextLowerDriver反回是Serial2 ??

驱动写作过程中,除要注意c/c++源码外,inf文件也是绝对十分关键的.
inf文件其中一项责任师负责写注册表,而向硬件的枚举,驱动程序的加载,堆栈的建立哪一项能离地开注册表

驱动写作过程中,除要注意c/c++源码外,inf文件也是绝对十分关键的.

我的inf问题在那里??
我贴上inf的原因是我知这重要 !!
