USB功能客户端开发WinCE 6.0

用于开发自定义USB功能客户端驱动程序（IMX51平台）。我指的是standerd serial usb功能客户端驱动程序。我选择了usb otg客户端 和目录项中的串行支持。还更改了platform.reg文件中的默认客户端驱动程序。
我建立了图片。 通过启动选项启用KITL并加载到目标。 usbfn.dll和serialusbfn.dll未加载。我禁用了KITL并将相同的图像加载到目标。我通过超级终端usbfn.dll和serialusbfn.dll分析调试消息是
loading。我的KITL传输设置为以太网。我不知道为什么KITL与USB功能客户端驱动程序发生冲突。任何人都面临这个问题。我使用的是IMX51 EVK。

For developing custom USB Function Client driver (IMX51 platform). I am referring standerd serial usb function client driver. I selected usb otg client  and serial support in catalog items. Also changed default client driver in platform.reg file. I built image. Enabled KITL through Boot options and loaded to target. usbfn.dll and serialusbfn.dll not loaded. I disabled KITL and loaded same image to target. I analyzed debug message through hyperterminal usbfn.dll and serialusbfn.dll are loading. My KITL transport set to ethernet. I dont have any idea why KITL clashing with USB Function client driver. Anybody faced this issue. I am using IMX51 EVK.
