无法使用 USB 无线网卡

我用的是迅捷的 FW150UH 免驱动版 2.0 的 USB 无线网卡。系统安装时一直插着。系统启动后我发现无线网卡没有启动———指示灯未亮,将其重新插入时系统将它当作 U 盘打开(它似乎有多个分区,一个分区是其运行文件是无法显示出来并打开的,另一分区储存着图中的文件,并且迅速地重复挂载卸载。Screenshot_20210710_110513 以下是 lsmod 输出结果

它还是给你挂了个分区让你装 Windows 上的驱动,你查一下它什么芯片找驱动装一下吧

你可能需要用 usb_modeswitch 来从 storage 模式切换成网卡模式
我查了一下资料这个网卡应该是 RTL8188EU,可能是支持的,手里没有类似的设备,你需要测试一下

有编译好的驱动可以试试看
