To 设备加载的问题
本人使用的硬件是Ez-usb fx2系列68013芯片
但是怎么

NTSTATUS
Ezusb_PnPAddDevice(
IN PDRIVER_OBJECT DriverObject,
IN PDEVICE_OBJECT PhysicalDeviceObject
)
/*++
Routine Description:
This routine is called to create a new instance of the device

Arguments:
DriverObject - pointer to the driver object for this instance of Ezusb
PhysicalDeviceObject - pointer to a device object created by the bus

Return Value:
STATUS_SUCCESS if successful,
STATUS_UNSUCCESSFUL otherwise

--*/
{
NTSTATUS ntStatus = STATUS_SUCCESS;
PDEVICE_OBJECT fdo = NULL;
PDEVICE_EXTENSION pdx;

WCHAR KernelDeviceNameBuffer[] = L "\\Device\\Ezusb-0 ";
UNICODE_STRING KernelDeviceNameUnicode;
WCHAR UserDeviceLinkBuffer[] = L "\\DosDevices\\Ezusb-0 ";
UNICODE_STRING UserDeviceLinkUnicode;
RtlInitUnicodeString (&KernelDeviceNameUnicode,
KernelDeviceNameBuffer);//&KernelDeviceNameUnicode

Ezusb_KdPrint(( "enter Ezusb_PnPAddDevice\n "));

ntStatus = IoCreateDevice (DriverObject,
sizeof (DEVICE_EXTENSION),
NULL,
FILE_DEVICE_UNKNOWN,
0,
FALSE,
&fdo);

if (NT_SUCCESS(ntStatus))
{

pdx = fdo-> DeviceExtension;

/*RtlInitUnicodeString (&UserDeviceLinkUnicode,
UserDeviceLinkBuffer);

ntStatus = IoCreateSymbolicLink (&UserDeviceLinkUnicode,
&KernelDeviceNameUnicode);

RtlCopyMemory(pdx-> DeviceLinkName,
UserDeviceLinkBuffer,
sizeof(UserDeviceLinkBuffer));
*/
fdo-> Flags &= ~DO_DEVICE_INITIALIZING;

fdo-> Flags |= DO_DIRECT_IO;
pdx-> PhysicalDeviceObject=PhysicalDeviceObject;

pdx-> StackDeviceObject =
IoAttachDeviceToDeviceStack(fdo, PhysicalDeviceObject);

ASSERT (pdx-> StackDeviceObject != NULL);

pdx-> usage = 1;
pdx-> OpenHandles++;
KeInitializeEvent(&pdx-> evRemove,
NotificationEvent,
FALSE); }

Ezusb_KdPrint(( "exit Ezusb_PnPAddDevice (%x)\n ", ntStatus));

return ntStatus;
}

本人只要使用设备描述符L "\\Device\\Ezusb-0 "; ,这个些代码,编译出来的驱动程序就不能正常加载,加载到一半时就出问题,代码31,请问高手这是怎么回事,这例程都是一些例子程序中拷贝过来,应该没有问题啊


[解决办法]
编译能通过么
