RNDIS“复合设备”无法启动

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

PC正在运行Win7 32位,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,一切都正常。但是,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”的问题。

我用USB分析器跟踪了USB数据流,发现Windows驱动程序在“设置配置”之后没有发送初始化消息。

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接口必须是复合器件的第一和第二。这个问题虽然解决了,但还是令我费解。

希望这张便条能帮助其他遇到类似问题的人。

对于那些遇到这个线程的人来说,因为RNDIS和windows代码10错误有类似的问题,使用内置的configfs libcomposite设备,经过大量的module搜索,在因特网上浏览代码,libcomposite模块中的代码……我发现,如果我在slot复合模块之后强制加载usb_f_rndis模块,而不是修补驱动程序,我可以绕过它,这将迫使usb_f_rndis进入第一个和第二个iad插槽。当您在configfs中添加设备时,and组合设备的其余模块将加载,Windows将对此感到满意。

此外,要强制windows加载正确的驱动程序,请确保设置了os_desc内容。这里有一个很好的指南,它是:http://irq5.io/2016/12/22/raspberry-pi-zero-as-multiple-usb-gadgets/

正如我在评论提到预加载解决方案的答案时所说的那样,在使用configfs设置复合小工具时,我无法预先加载usb_f_rndis模块来产生任何不同。但是,我发现函数目录链接到配置目录的顺序会产生影响。

代码语言:javascript
复制
ln -s gadget/functions/acm.usb0 gadget/configs/c.1
ln -s gadget/functions/rndis.usb0 gadget/configs/c.1

给我留下了一个功能强大的USB串口,但是RNDIS适配器坏了,显示错误代码10。

代码语言:javascript
复制
ln -s gadget/functions/rndis.usb0 gadget/configs/c.1
ln -s gadget/functions/acm.usb0 gadget/configs/c.1

给我一个功能串口和RNDIS适配器。问题当然是,随着时间的推移,这种情况会有多稳定。我怀疑这可能是一种侥幸,类似于usb_f_rndis的预加载技巧。

顺便说一下,这是在Debian 10.9和5.15.74-v7l+上。
