usb开发－－ActivateConfiguration

我在使用ActivateConfiguration（）函数时，返回是成功的，但我的kusbpipe对象都没有打开，进一步测试发现，执行ActivateConfiguration（）后，m_Lower中m_Lower.PipeArray().MaxInserted()值为：0x09，而m_Lower.InterfaceArray().MaxInserted()值为：0x00,即是m_Interface对象没有添加到InterfaceArray数组中，请各位大侠指点一下。我的部分源程序如下：Usb7C68Dev::Usb7C68Dev(PDEVICE_OBJECT Pdo, ULONG Unit) :
KPnpDevice(Pdo, NULL)
{
t << "Entering Usb7C68Dev::Usb7C68Dev (constructor)\n";


// Check constructor status
    if ( ! NT_SUCCESS(m_ConstructorStatus) )
{
   return;
}

// Remember our unit number
m_Unit = Unit;

// Initialize the lower device
m_Lower.Initialize(this, Pdo);

// Initialize the interface object.  The wizard generates code
// to support a single interface.  You may create and add additional
// interfaces.  By default, the wizard uses InterfaceNumber 0 (the
// first interface descriptor), ConfigurationValue 1 (the first
// configuration descriptor), and initial interface alternate
// setting of 0.  If your device has multiple interfaces or alternate
// settings for an interface, you can add additional KUsbInterface
// objects or adjust the parameters passed to this function.
m_Interface.Initialize(
m_Lower, //KUsbLowerDevice
0, //InterfaceNumber
1, //ConfigurationValue
0 //Initial Interface Alternate Setting
);

// Initialize each Pipe object
m_EndpIn1.Initialize(m_Lower, 0x81, 32);
m_EndpOut1.Initialize(m_Lower, 0x1, 32);

m_EndpIn8.Initialize(m_Lower, 0x88, 64);
m_EndpOut8.Initialize(m_Lower, 0x8, 64);

    // Inform the base class of the lower edge device object
SetLowerDevice(&m_Lower);
