求助 内核中使用IOCTL_STORAGE_QUERY_PROPERTY区分USB与磁盘卷

将我的过滤驱动文件SYS 挂载在{71A27CDD-812A-11D0-BEC7-08002BE2092F}存储卷类下
 
在adddevice函数中对于过滤到的设备发送IOCTL_STORAGE_QUERY_PROPERTY以区分是磁盘卷还是USB卷
但是函数始终不成功 返回参数失败 c00000EF
代码如下NTSTATUS
AddDevice(
 IN PDRIVER_OBJECT DriverObject,
 IN PDEVICE_OBJECT PhysicalDeviceObject)
{
  IsUSBVolume = FALSE;
  QueryDeviceType(PhysicalDeviceObject ,&IsUSBVolume)
.......
}
 
QueryDeviceType用的是驱网的代码
就是新建一个IRP 发送出去查询_STORAGE_QUERY_PROPERTY
 
但是在IoCallDriver老是返回失败 不知道什么原因
代码如下
 

NTSTATUS
QueryDeviceType(PDEVICE_OBJECT  DiskDeviceObject,BOOL* IsUSBVolume)
{
 NTSTATUS    status = STATUS_UNSUCCESSFUL;
 KEVENT      WaitEvent;
 STORAGE_PROPERTY_QUERY  Query;
 PIRP NewIrp;
 UCHAR pBuffer[sizeof(STORAGE_DEVICE_DESCRIPTOR)+512];
 PSTORAGE_DEVICE_DESCRIPTOR Descriptor;
 IO_STATUS_BLOCK IoStatus;
 
 PAGED_CODE();
 
 NewIrp = IoBuildDeviceIoControlRequest(IOCTL_STORAGE_QUERY_PROPERTY, DiskDeviceObject,
   (PVOID)&Query, sizeof(STORAGE_DEVICE_DESCRIPTOR), (PVOID)pBuffer,
   sizeof(STORAGE_DEVICE_DESCRIPTOR) * 4, FALSE, &WaitEvent, &IoStatus);
 if (NULL == NewIrp)   // can't create new irp
 {
  DbgPrint(" BusTypeUnknown \n");
  return status;
 }
 status = IoCallDriver(DiskDeviceObject, NewIrp);
 if (status == STATUS_PENDING)
 {
  status = KeWaitForSingleObject(&WaitEvent, Executive, KernelMode, FALSE, NULL);
  status = IoStatus.Status;
 }
 if (!NT_SUCCESS(status))
 {
  DbgPrint(" BusTypeUnknown \n");
  return status;
 }
 Descriptor = (PSTORAGE_DEVICE_DESCRIPTOR)pBuffer;
 if(Descriptor->BusType == BusTypeUsb)
 {
  DbgPrint("GetStorageDeviceBusType  SUCCEED: %d DevType:%x \n   ",
         Descriptor->BusType, DiskDeviceObject->DeviceType);
  *IsUSBVolume = TRUE;
 }
 return status;
}
