打开设备 怎么无法通讯？

我正在做串口设备的驱动开发，类似于一个鼠标，所以我的adddevice 例程中IoCreateDevice(Driver,
                            sizeof(DEVICE_EXTENSION),
                          NULL, // no name for thisFilter DO
                            FILE_DEVICE_SERIAL_MOUSE_PORT,
                            0,
                            FALSE,
                            &device);
然后注册设备接口
IoRegisterDeviceInterface(PDO,&Touch_GUID,NULL,&deviceExtension->ifSymLinkName);
启动接口
IoSetDeviceInterfaceState(&deviceExtension->ifSymLinkName,TRUE);
在驱动安装完后我打开设备
HANDLE GetDeviceViaInterface( GUID* pGuid, DWORD instance);

int main(int argc, char* argv[])
{
int TestNo = 1;

printf("\nWdm1Test\n");

/////////////////////////////////////////////////////////////////////////
// Open device
printf("\nTest %d\n",TestNo++);
HANDLE hTouch = GetDeviceViaInterface((LPGUID)&Touch_GUID,0);
if( hTouch==NULL)
{
printf("XXX  Could not find open Wdm1 device\n");
return 1;
}
printf("     Opened OK\n");
if( !DeviceIoControl( hTouch, IOCTL_SETB_RECTIFY_FLAG,
NULL, 0, // Input
NULL, 0, // Output
NULL, NULL))
printf("XXX  SET THE RECTIFY FLAG FAILURE \n");
else
printf(" SET THE RECTIFY FLAG SUCEED ");



/////////////////////////////////////////////////////////////////////////
 
/////////////////////////////////////////////////////////////////////////
// Close device
printf("\nTest %d\n",TestNo++);
if( !CloseHandle(hTouch))
printf("XXX  CloseHandle failed %d\n",GetLastError());
else
printf("     CloseHandle worked\n");

/////////////////////////////////////////////////////////////////////////

return 0;
}

/////////////////////////////////////////////////////////////////////////////
// GetDeviceViaInterface: Open a handle via a device interface

HANDLE GetDeviceViaInterface( GUID* pGuid, DWORD instance)
{
// Get handle to relevant device information set
HDEVINFO info = SetupDiGetClassDevs(pGuid, NULL, NULL, DIGCF_PRESENT | DIGCF_INTERFACEDEVICE);
if(info==INVALID_HANDLE_VALUE)
{
printf("No HDEVINFO available for this GUID\n");
return NULL;
}

// Get interface data for the requested instance
SP_INTERFACE_DEVICE_DATA ifdata;
ifdata.cbSize = sizeof(ifdata);
if(!SetupDiEnumDeviceInterfaces(info, NULL, pGuid, instance, &ifdata))
{
printf("No SP_INTERFACE_DEVICE_DATA available for this GUID instance\n");
SetupDiDestroyDeviceInfoList(info);
return NULL;
}

// Get size of symbolic link name
DWORD ReqLen;
SetupDiGetDeviceInterfaceDetail(info, &ifdata, NULL, 0, &ReqLen, NULL);
PSP_INTERFACE_DEVICE_DETAIL_DATA ifDetail = (PSP_INTERFACE_DEVICE_DETAIL_DATA)(new char[ReqLen]);
if( ifDetail==NULL)
{
SetupDiDestroyDeviceInfoList(info);
return NULL;
}

// Get symbolic link name
ifDetail->cbSize = sizeof(SP_INTERFACE_DEVICE_DETAIL_DATA);
if( !SetupDiGetDeviceInterfaceDetail(info, &ifdata, ifDetail, ReqLen, NULL, NULL))
{
SetupDiDestroyDeviceInfoList(info);
delete ifDetail;
return NULL;
}

printf("Symbolic link is %s\n",ifDetail->DevicePath);
// Open file
HANDLE rv = CreateFile( ifDetail->DevicePath,
  //GENERIC_READ,
GENERIC_WRITE,
 //0,
//0,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
if( rv==INVALID_HANDLE_VALUE) rv = NULL;

delete ifDetail;
SetupDiDestroyDeviceInfoList(info);
return rv;
}
我发现了一个怪问题，再用createdevice打开设备时，不能包括GENERIC_READ，一旦包括了它就无法打开设备，档案上面的程序打开设备后，利用DeviceIoControl( hTouch, IOCTL_SETB_RECTIFY_FLAG,NULL, 0,//input
NULL, 0, // Output NULL, NULL))跟设备驱动通讯时却]发现驱动没有姐收到
IRP_MJ_DEVICE_CONTrol消息
NTSTATUS
DeviceControl(
IN PDEVICE_OBJECT   DeviceObject,
    IN PIRP             Irp
    )
{
    PIO_STACK_LOCATION      irpSp;
    PDEVICE_EXTENSION       deviceExtension;
    NTSTATUS                status;
    
    deviceExtension = DeviceObject->DeviceExtension;
Irp->IoStatus.Information = 0;
    DebugPrint("Device io control entered");
     irpSp=IoGetCurrentIrpStackLocation(Irp);

status = IoAcquireRemoveLock(&deviceExtension->RemoveLock, Irp);
    if (!NT_SUCCESS(status)) {
        Irp->IoStatus.Status = status;
        IoCompleteRequest(Irp, IO_NO_INCREMENT);
        return status;
    }
switch(irpSp->Parameters.DeviceIoControl.IoControlCode){
case IOCTL_SETB_RECTIFY_FLAG:
    deviceExtension->CalibrateFlag=InRectify ;
    DebugPrint("the device is in calibrateflag procession");
status = STATUS_SUCCESS;
break;

default:
  status = STATUS_INVALID_DEVICE_REQUEST;
        break;
    }
    Irp->IoStatus.Status = status;
    IoCompleteRequest(Irp, IO_NO_INCREMENT);

    IoReleaseRemoveLock(&deviceExtension->RemoveLock, Irp);
DebugPrint("device io control exit");
return status;
}
不知道原因在那里，那位大虾能给小弟指条明路啊

你的驱动是什么？
