Question 2

你的设备几乎肯定是这样的：

alias:          sdio:c*v02D0d4345*

这是来自驱动程序的别名字段韓國它会根据你的 dmesg 在启动时加载。我们从你的 dmesg 中得到了线索：

brcmfmac: brcmf_fw_map_chip_to_name: using brcm/brcmfmac43455-sdio.bin for chip 0x004345(17221) rev 0x000006

唯一的“4345”别名正如我上面引用的那样。

正如你在问题中提到的，各种消息来源表明，司机負責人是首选。但是，找不到最新版本的驱动程序来编译和尝试。您引用的代码的最后一次更新是在六年前更新的。它不会在任何最新的内核上编译。

最后，通常可靠的 Wikidevi 报道： https://wikidevi.com/wiki/Talk:Linux_Wi-Fi_device_entries#02d0_-_Broadcom

02d0:4345 - BCM4345（旧版本 BCM43455） - 不支持的 SDIO ID：SD\VID_02D0&PID_4345

总之，尽管韓國加载并加载固件，它不会驱动设备。我很遗憾地同意；该设备不受支持。
