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

呵呵!
