蓝牙无法工作

我的蓝牙适配器无法在 Linux mint（和其他发行版）上运行。我已经尝试了在互联网上可以找到的所有可能的解决方案。我什至尝试了基于 Arch 和 ubuntu 的不同发行版，但没有用。

我的加密狗非常通用，在 Windows 上运行良好。它不需要任何驱动程序或软件。我有一些dmesg和其他日志，请看一下。

$ dmesg | grep Blue

我也尝试过用blueman代替blueberry，但没有用。

是的，我的 BT 已连接，但输出显示

$ sudo bluetoothctl
Agent registered
[bluetooth]# show
No default controller available

和

答案1

的输出dmesg | grep Blue告诉您内核启动了自己的蓝牙支持，而不是它已检测到您的硬件。

lsusb 输出显示属于具有内核支持的加密狗的 VID（供应商 ID）和 PID（产品 ID）在过去。

然而，在当前版本的linux内核中，好像没有支持。
