前言：鲁班猫2系统镜像为：lubancat-rk3568-debian10-xfce-full-20240510_update.img。

接上篇在鲁班猫2安装Tenda USB WIFI的驱动。我现在手头上有了5个厂商的30元以下的USB WIFI：

Tenda：W311MI
EDUP：EP-AX300
COMFAST：CF-940AX
MERCURY：UX3
UGREEN：CM760

同样的AIC8800

每一家都提供了Linux设备驱动包。从驱动包的名称或者从deb包中提取的驱动源码可以知道他们都是基于AIC8800系列芯片。

不一样的结果

当我将后来买的四款USB WIFI依次插入Tenda USB WIFI可以正常使用的鲁班猫2上时，分歧出现了。

EDUP和COMFAST正常工作，无线网卡设备正常出现。
MERCURY和UGREEN，没有看到任何无线网络设备。

该dmesg出场了

以下依次列举插入五款USB WIFI之后的系统log。
