Usb RNDIS“；“复合装置”；无法启动

我正在开发一个RNDIS复合设备，其中包括一个RNDIS设备、一个usbnet设备、一个调制解调器设备和一个自定义CDC设备

电脑运行的是32位Win7，我使用的是默认的RNDIS驱动程序。 当我只使用RNDIS设备回答Windows枚举时，一切正常。 但当我将所有4个设备作为复合设备组合到描述符中时，Windows仍然正确枚举，其他3个设备工作正常，但RNDIS设备遇到“无法启动错误代码10”问题

我用USB分析仪跟踪USB数据流，发现Windows RNDIS驱动程序在“设置配置”后未发送RNDIS初始化消息

复合设备描述符如下所示：

让我回答我自己的问题，我已经解决了这个问题：

RNDIS IAD接口必须是复合设备的第一个和第二个接口。 这个问题虽然解决了，但仍然困扰着我

---

希望本说明能帮助其他遇到类似问题的人。

对于那些遇到此问题的人，因为在使用内置configfs libcomposite设备、进行了大量的谷歌搜索并在互联网上查看代码之后，您在RNDIS和windows code 10错误方面遇到了类似的问题，libcomposite模块中的代码。。。。。我发现，如果我在libcomposite模块之后直接强制加载usb_f_rndis模块，而不是修补驱动程序，我可以解决这个问题，这会强制usb_f_rndis到第一个和第二个iad插槽。当您在configfs中添加设备时，libcomposite设备的其余模块将被加载，Windows将对此感到满意

---

另外，要强制windows加载正确的驱动程序，请确保设置了os_desc。这里有一个很好的指南：

解决方案是什么，真的吗？：）你在Linux驱动程序中更改了什么吗？（编辑：我意识到你制作了一个定制的合成。我对标准设备有一个问题，它也是一个合成设备，尽管只有RNDIS和CDC以太网。它在Windows中也会得到“代码10”，尽管RNDIS配置可能是合成描述符中的第一个-奇怪…@mariocao，你是如何发现的？外面有医生吗？谢谢，在上提到了此解决方法
