    HardwareDeviceInfo = SetupDiGetClassDevs(

                             InterfaceGuid,

                             NULL,

                             NULL,

                             (DIGCF_PRESENT | DIGCF_DEVICEINTERFACE));

执行成功，但是紧接着的

    bResult = SetupDiEnumDeviceInterfaces(HardwareDeviceInfo,

                                              0,

                                              InterfaceGuid,

                                              19,

                                              &DeviceInterfaceData);

失败。

SetupDiEnumDeviceInterfaces returns TRUE if the function completed without error. If the function completed with an error, FALSE is returned and the error code for the failure can be retrieved by calling GetLastError.

调用了DeviceInterfaceData.cbSize = sizeof(SP_DEVICE_INTERFACE_DATA);没有？
还有就是
MemberIndex
A zero-based index into the list of interfaces in the device information set. The caller should call this function first with MemberIndex set to zero to obtain the first interface. Then, repeatedly increment MemberIndex and retrieve an interface until this function fails and GetLastError returns ERROR_NO_MORE_ITEMS.
