Dear all:
I want to send usb control transfer for U disk,In busHound we can send usb control transfer,but I don't kown how to send it by VC11,I find some information about CTL from msdn.below is my test source code.

static /*const*/ GUID GUID_DEVINTERFACE_USB_DEVICE = 
	{ 0xA5DCBF10L, 0x6530, 0x11D2, { 0x90, 0x1F, 0x00, 0xC0, 0x4F, 0xB9, 0x51, 0xED } };
	int i;
	DWORD ErrorInfo_0 , ErrorInfo_1 ,ErrorInfo_2;
	PSP_INTERFACE_DEVICE_DETAIL_DATA ifDetail;
   // Get handle to relevant device information set
    HDEVINFO info = SetupDiGetClassDevs(&GUID_DEVINTERFACE_USB_DEVICE, NULL, NULL, DIGCF_PRESENT | DIGCF_INTERFACEDEVICE);
    if(info==INVALID_HANDLE_VALUE)
    {
        printf("No HDEVINFO available for this GUID\n");
        return ;
    }
	for(i = 0; i < 100; i ++)
	{
		// Get interface data for the requested instance
		SP_INTERFACE_DEVICE_DATA ifdata;
		ifdata.cbSize = sizeof(ifdata);
		if(!SetupDiEnumDeviceInterfaces(info, 0, &GUID_DEVINTERFACE_USB_DEVICE, i, &ifdata))
		{
			printf("No SP_INTERFACE_DEVICE_DATA available for this GUID instance\n");
			SetupDiDestroyDeviceInfoList(info);
			return ;
		}

		// Get size of symbolic link name
		DWORD ReqLen;
		SetupDiGetDeviceInterfaceDetail(info, &ifdata, NULL, 0, &ReqLen, NULL);
		ifDetail = (PSP_INTERFACE_DEVICE_DETAIL_DATA)(new char[ReqLen]);
		if( ifDetail==NULL)
		{
			SetupDiDestroyDeviceInfoList(info);
			return ;
		}

		// Get symbolic link name
		ifDetail->cbSize = sizeof(SP_INTERFACE_DEVICE_DETAIL_DATA);
		if( !SetupDiGetDeviceInterfaceDetail(info, &ifdata, ifDetail, ReqLen, NULL, NULL))
		{
			SetupDiDestroyDeviceInfoList(info);
			delete ifDetail;
			return ;
		}
		CString path = ifDetail->DevicePath;
		if(path.Find(_T("vid_19d2&pid_1257")) > 0)
		{
			MessageBox(_T("find ok"));
			break;
		}

	}

    printf("Symbolic link is %s\n",ifDetail->DevicePath);
    // Open file
    HANDLE rv = CreateFile( ifDetail->DevicePath, 
        GENERIC_READ | GENERIC_WRITE,
        FILE_SHARE_READ | FILE_SHARE_WRITE,
		NULL, OPEN_EXISTING, FILE_FLAG_OVERLAPPED, NULL);
    if( rv==INVALID_HANDLE_VALUE) rv = NULL;

	delete ifDetail;
    SetupDiDestroyDeviceInfoList(info);

	WINUSB_INTERFACE_HANDLE interfacehandle;
	BOOL result = WinUsb_Initialize(rv, &interfacehandle);
	ErrorInfo_0 = GetLastError();
	if(ErrorInfo_0 == ERROR_INVALID_HANDLE)
		MessageBox(_T("1"));
	else if(ErrorInfo_0 == ERROR_NOT_ENOUGH_MEMORY)
		MessageBox(_T("2"));
	else if(ErrorInfo_0 == ERROR_BAD_DEVICE)
		MessageBox(_T("3"));
	if(!result)
	{
		MessageBox(_T("win usb init fail"));
		return;
	}

Now I can get my u disk device handle,but I didn't get interfacehandle,the function of GetLastError() return ERROR_NOT_ENOUGH_MEMORY value.This is urgent for me,if your give us some advice I am appreciated,thank you in advance.
