高分请教 Usb: Board did not accept configuration URB 问题！！！

我编译了一驱动程序，当跟踪时出现以下错误信息：
5843.938   Default   Usb: Board did not accept configuration URB

我的这部分原代码是：
...
NTSTATUS UsbDevice::OnStartDevice(KIrp I)
{
t << "Entering UsbDevice::OnStartDevice/n";

NTSTATUS status = STATUS_UNSUCCESSFUL;

AC_STATUS acStatus = AC_SUCCESS;

I.Information() = 0;
           status = m_Lower.Preconfigure();
if(status==STATUS_SUCCESS)
t << "Get USB Configuration OK/n";

acStatus = m_Lower.ActivateConfiguration(1
 // ConfigurationValue 1 (the first configuration)
);


switch (acStatus)
{
case AC_SUCCESS:
t << "USB Configuration OK/n";
status = STATUS_SUCCESS;
break;

case AC_COULD_NOT_LOCATE_INTERFACE:
t << "Could not locate interface/n";
break;

case AC_COULD_NOT_PRECONFIGURE_INTERFACE:
t << "Could not get configuration descriptor/n";
break;

case AC_CONFIGURATION_REQUEST_FAILED:
t << "Board did not accept configuration URB/n";
break;

case AC_FAILED_TO_INITIALIZE_INTERFACE_OBJECT:
t << "Failed to initialize interface object/n";
break;

case AC_FAILED_TO_GET_DESCRIPTOR:
t << "Failed to get device descriptor/n";
break;

case AC_FAILED_TO_OPEN_PIPE_OBJECT:
//NOTE: this may not be an error.  It could mean that
//the device has an endpoint for which a KUsbPipe object has
//not been instanced.  If the intention is to not use this endpoint,
//then it's likely not a problem.  
status = STATUS_SUCCESS;
t << "Failed to open pipe object/n";
break;

default:
t << "Unexpected error activating USB configuration/n";
break;
}


请问究竟错误在什么地方，该如何解决呢？谢谢各位了。
（上面switch循环是自动生成的，应该没有问题）

看看你的固件是否正确

固件检查过了，没有问题，哪位老大帮看看啊！！
