Ce6.0下利用COMPOSITEFN驱动实现串口和U盘成为复合设备的问题 [复制链接]

我们在用三星ideal6410开发板，想利用C:\WINCE600\PUBLIC\COMMON\OAK\DRIVERS\USBFN\CLASS\COMPOSITEFN驱动来实现串口和优盘的复合设备。我们的具体做法如下：
1.        将上面目录compositefn文件夹移植到bsp\src\driver下面，接着将compositefn编译成流驱动compositefn.dll，然后通过设置注册表如下：
……………………………………………………………………………………………
IF BSP_USBFNCLASS == COMPOSITEFN                    
        [HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers]
           "DefaultClientDriver"=- ; erase previous default
        "DefaultClientDriver"="CompositeFN"
        [HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers\CompositeFN]
          "ClientDriverList"=multi_sz:"Mass_Storage_Class","Serial_Class"
          "bcdDevice"=dword:0
          "Prefix"="UFC"
          "Dll"="compositefn.dll"
          "Index"=dword:0
          "Order"=dword:53
          "ManufacturerString"="COMPOSITE DEVICE"
          "MaxPacketSize"=dword:40
          "VendorID"=dword:045E
          "ProductID"=dword:00CE
          "Attributes"=multi_sz:"80","81"
          "xFriendlyName"="COMPOSITE"
ENDIF BSP_USBFNCLASS
;------------ USB Function Serial Driver --------------------------------------
IF BSP_USBFNCLASS == SERIAL
[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers]
        "DefaultClientDriver"="Serial_Class"
[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers\Serial_Class]
        "UFC_DefaultClient"=dword:1
        "UFC_FriendlyName"=LOC_USBFN_SERIAL_NAME
        "UFC_idVendor"=dword:0547
        "UFC_Manufacturer"=LOC_USBFN_SERIAL_MANUFACTURER
        "UFC_idProduct"=dword:2720
        "UFC_Product"=LOC_USBFN_SERIAL_PRODUCT
        "UFC_Index"=dword:5
"UFC_Configurations"=multi_sz:81
        "UFC_FunctionClass"=dword:0E
        "UFC_FunctionProtocol"=dword:00
        "UFC_FunctionSubClass"=dword:03
        "UFC_bcdDevice"=dword:0

ENDIF BSP_USBFNCLASS
;-------------------------------------------------------------------------

;------------ USB Function Mass Stroge Driver ---------------------------------
IF BSP_USBFNCLASS == MASS_STORAGE
[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers]
        "DefaultClientDriver"="Mass_Storage_Class"
[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers\Mass_Storage_Class]
"UFC_DefaultClient"=dword:0
        "Dll"="usbmsfn.dll"
        "UFC_InterfaceSubClass"=dword:06
        "UFC_InterfaceProtocol"=dword:50
"UFC_Configurations"=multi_sz:80
        "UFC_FunctionClass"=dword:0E
        "UFC_FunctionProtocol"=dword:00
        "UFC_FunctionSubClass"=dword:03
        "UFC_bcdDevice"=dword:0
        "UFC_DeviceName"="DSK3:"
        "UFC_FriendlyName"="Mass Storage"
        "UFC_idVendor"=dword:045E
        "UFC_Manufacturer"="Generic Manufacturer (PROTOTYPE--Remember to change idVendor)"
        "UFC_idProduct"=dword:FFFF
        "UFC_Product"="Generic Mass Storage (PROTOTYPE--Remember to change idVendor)"
……………………………………………………………………………………………………
在最后加入：
;CPF
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\CompositeFN]
         "ClientDriverList"=multi_sz:"Mass_Storage_Class","Serial_Class"
          "Prefix"="UFC"
          "Dll"="compositefn.dll"
   "Index"=dword:1
          "Order"=dword:53
          "ManufacturerString"="COMPOSITE DEVICE"
          "MaxPacketSize"=dword:40
          "VendorID"=dword:045E
          "ProductID"=dword:00CE
          "Attributes"=multi_sz:"80","81"
          "xFriendlyName"="Serial on USB" ; experimenting

并改写相应的platform.BIB，SMDK6410.bat文件，并在CMD窗口下设置环境变量如下：set   SYSGEN_USBFN_COMPOSITE=1。这样compositefn.dll就可以在系统启动的时候被自动加载。
通过实验，经编译通过的NK.EXE下载到我们的在ideal6410开发板上面，我们可以看到：在ideal6410上打开注册表，在driver\active\下面的23项，看到COMPOSITEFN.DLL已经被成功加载。
2通过DWN.EXE查看串口调试信息关键部分如下：
-OALIntrRequestSysIntr(irq = 96, sysIntr = 30)

说明ActiveKey =“Drivers\Active\23”时候，能够成功加载，而ActiveKey =“Drivers\Active\59”时候，出现了错误。具体错误通过加入调试信息也可以找到最根处：
是在C:\WINCE600\PUBLIC\COMMON\OAK\DRIVERS\USBFN\UFNCLIENTLIB\中的UfnClient.cpp这段程序：
xtern "C"

    LPCTSTR             pszActiveKey,

    )

    SETFNAME();
    DWORD dwRet;
    PUFN_CLIENT_INTERFACE pInterface = NULL;
    HANDLE hBusAccess = NULL;
    UFN_CLIENT_DATA ucd;
    BOOL fSuccess;
    if ( !pszActiveKey || !phDevice || !pFunctions || !ppvInterfaceInfo ) {
        dwRet = ERROR_INVALID_PARAMETER;
        DEBUGMSG(1, (_T("%s Invalid parameter.\r\n"),
            pszFname));
        goto EXIT;
    }
    pInterface = (PUFN_CLIENT_INTERFACE) LocalAlloc(LPTR, sizeof(UFN_CLIENT_INTERFACE));
    if (pInterface == NULL) {
                RETAILMSG(1, (_T("pInterface == NULL\r\n")));
        dwRet = GetLastError();
        DEBUGMSG(1, (_T("%s Could not allocate memory. Error %u\r\n"),
            pszFname, dwRet));
        goto EXIT;
    }

                RETAILMSG(1, (_T("%s  is IS UfnInitializeInterface.ActiveKey \n"), pszActiveKey));
    hBusAccess = CreateBusAccessHandle(pszActiveKey);
    if (hBusAccess == NULL) {
                RETAILMSG(1, (_T("pInterface == NULL\r\n")));
        dwRet = GetLastError();
        DEBUGMSG(1, (_T("%s Could not CreateBusAccessHandle. Error %u\r\n"),
            pszFname, dwRet));
        goto EXIT;
    }

    memset(&ucd, 0, sizeof(ucd));
    ucd.dwVersion = UFN_CLIENT_INTERFACE_VERSION;
    fSuccess = BusChildIoControl(hBusAccess, IOCTL_UFN_GET_CLIENT_DATA_EX, &ucd, sizeof(ucd));
    if (!fSuccess) {
                RETAILMSG(1, (_T("fSuccess chu\r\n")));///通过上面串口调试信息我们可以看到是在此处///////////////////////////////////////////////////////////////////////出错！！！
        dwRet = GetLastError();
        goto EXIT;
    }
compositefn驱动会被加载两次呢？是不是因为复合了两个设备啊？还有串口是不是不能作为一个设备同另外一个设备符合啊？
请搞过复合设备的高手指点迷津！！！小弟不胜感激！！！！[/color]

哎，没人回帖，友情帮顶一下吧。。。

怎么搞的，没人教我一下啊！！！郁闷了！

复合驱动，没搞过啊，比较复杂

emailli

我最近也在看这个，很多不明白的，一起学习一下。
问一下，你SMDK6410.bat文件怎么修改的，貌似修改SMDK6410.bat的UFNCLASS就直接可以加载你的驱动了。还有set SYSGEN_USBFN_COMPOSITE=1你是怎么样处理的？是sysgen还是就make一下就可以了。
我像你之前那么做的，能加载上compositefn驱动，但是想要复合的驱动加不上，在准备搞一搞

注册表配置增加一项：
[HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers\CompositeFN]  
  "DefaultPrefix"="UFC"
并删除类似"UFC_FunctionClass"的值

楼主，问题解决了吗？我最近也在搞这个
