Windbg !devstack命令

!devstack命令用于显示设备栈

不过这里只是以FDO为中心的所有USB设备信息。。

   DbgPrint("AddDevice: %p to %p->%p \n", deviceObject, deviceExtension->NextDeviceObject, PhysicalDeviceObject);

输出为：

AddDevice: FFFF880433B55510 to FFFF880433A2F810->FFFF8804339FB810

设备栈为:

1: kd> !devstack 0xffff8804`33b55510 
  !DevObj           !DrvObj            !DevExt           ObjectName
