我的蓝牙已打开并且可见，但它没有检测到任何设备并且也没有被其他设备检测到。
我知道还有很多类似的问题，但是所提出的解决方案似乎都不适合我。
下面列出了一些信息，如果有任何遗漏，请告诉我。

答案1
Linux 内核尚不支持此适配器。
要包含此适配器，您需要通过在终端中运行向 Launchpad 报告错误
ubuntu-bug linux
按照浏览器中的指示填写错误报告。
请包含输出
usb-devices | awk '/13d3/' RS=
对错误的描述。
您可以留下错误报告的链接并在评论中联系我。我会处理它。
修复这个问题不会花太多时间。我会建立一个测试模块，希望 BT 能够使用它。与此同时，支持将在某个时候达到稳定内核。
更新：该问题已在官方 Ubuntu 内核中修复。
