我现在碰到一个这样的驱动程序，它的入口例程如下：
ULONG
DriverEntry (
IN PDRIVER_OBJECT DriverObject,
IN PUNICODE_STRING RegistryPath
)
{
HW_INITIALIZATION_DATA HwInitData;
ULONG ReturnValue;
RtlZeroMemory(&HwInitData, sizeof(HwInitData));
HwInitData.HwInitializationDataSize = sizeof(HwInitData);
//
// Set the Adapter entry points for the driver
//
HwInitData.HwInterrupt = NULL; // HwInterrupt;
HwInitData.HwReceivePacket = AdapterReceivePacket;
HwInitData.HwCancelPacket = AdapterCancelPacket;
HwInitData.HwRequestTimeoutHandler = AdapterTimeoutPacket;
HwInitData.DeviceExtensionSize = sizeof(HW_DEVICE_EXTENSION);
HwInitData.PerRequestExtensionSize = sizeof(SRB_EXTENSION);
HwInitData.FilterInstanceExtensionSize = 0;
HwInitData.PerStreamExtensionSize = sizeof(STREAMEX);
HwInitData.BusMasterDMA = FALSE;
HwInitData.Dma24BitAddresses = FALSE;
HwInitData.BufferAlignment = 3;
HwInitData.DmaBufferSize = 0;
// Don't rely on the stream class using raised IRQL to synchronize
// execution. This single paramter most affects the overall structure
// of the driver.
HwInitData.TurnOffSynchronization = TRUE;
ReturnValue = StreamClassRegisterAdapter(DriverObject, RegistryPath, &HwInitData);
return ReturnValue;
}
我现在不知道怎么跟这样的驱动程序通讯啊，大虾们帮帮忙啊。
