蓝牙hci0未被相关检测

Question

我知道MEDIATEK MT7922应该能够处理蓝牙，但我不能打开它。我试过从重新安装布卢兹，百日咳等等.

刚才我说，尽管MT7922是PCIe，但系统似乎认为我的蓝牙是USB类型的富士康。

正如您所看到的，没有结果：

kepler-22b@Horizon-A082:~$

我重新启动电脑，然后再试一次：

通过内核升级修复。

我的系统现在运行在22.04 LTS上，因为它为Nvidia驱动程序增加了22.10个复杂的东西，而不是修复问题，而是增加了更多。

我并不拥有这些知识来理解上述链接的每一条指令所做的事情，但它解决了问题，直到更新的发行版解决了这些问题。如果有人解释或指出说明中是否有问题，我将不胜感激。
