把OTG配上USB网卡功能,PC机重启时USB网卡不能正常使用

本帖最后由 hapbir 于 2022-11-22 16:55 编辑

我参考wiki教程[https://wiki.t-firefly.com/Core-3328-JD4/ubuntu_manual.html#usb-yi-tai-wang],在OTG口开启USB网卡功能。
1> PC(CentO S7.9、Ubuntu18.04)已开机,初次连接USB线到OTG口;

2> 接着USB线重启PC;
在PC上枚举的网卡名不太一样,如enp0s29f7u6c2i1,这样的网卡名即使配置IP也不能用。
重新插拔USB线或在板子上重新加载那些驱动文件后正常,PC上的网卡名变为enp0s29f7u6c2,配置IP后可用。

PC(CentOS7.9)上一段dmesg日志

请问一下这是哪儿的问题,是我配错了么?

自己回答一下吧。
找了一些资料说是Linux对TNDIS支持不太好(具体情况不太了解)。把“RNDIS support (NEW)”取消,在Linux系统上试倒是正常了。
