蓝牙未发现设备，驱动程序当前（Kubuntu 24.04）

  • 772

本周刚开始使用 Kubuntu (24.04)，并尝试设置好一切，我发现蓝牙检测不到任何设备（我尝试过将多个设备置于配对模式，这些设备在其他操作系统和我的 Android 手机上运行）。我已经找到了如何检查蓝牙服务的状态、获取设备信息的方法，一切似乎都很正常，驱动程序也正确，但我无法发现任何设备。任何有关尝试的建议都将不胜感激。

以下输出使我认为蓝牙服务和设备已启动并正在运行......

但在本教程的这一步，他们的蓝牙开始发现设备，而我的却没有。它也没有发现任何带有内置蓝牙 GUI 或 blueman 的设备。

输出sudo dmesg | grep -i 'blue'：

并且lspci -nnk | grep -iA2 net 由于在类似的问题中专门要求输出这一点：

对我来说，这看起来像是设备正在工作、被发现、有驱动程序并且正确连接到蓝牙服务，而且我知道它在 Windows 上测试过后可以正常工作，但有些东西阻止它发现任何设备。任何建议都将不胜感激！

（注意：我不知道这是否相关，但正如所提到的，该系统与 Windows 是双启动的。作为解决 wifi 问题的一部分，我已经在 Windows 中禁用了快速启动。）

    在终端中检查mokutil --sb，因为必须禁用安全启动，因为此内核模块不会被签名。然后在终端中

    sudo apt install git dkms
git clone https://github.com/jeremyb31/bluetooth-6.8.git
sudo dkms add ./bluetooth-6.8
sudo dkms install btusb/4.1

    重启

    我在内核 6.8 中的 btusb 源代码中添加了以下代码 https://github.com/jeremyb31/bluetooth-6.8/commit/0f3b823eea66adf1fbabc865f89484ea486f6e65
