检测到蓝牙适配器，但它在 Ubuntu 22.04 中无法工作

Question

我已经安装了 Ubuntu 22.04 (Jammy Jellyfish)，但在某些时候我的蓝牙连接停止工作。

我有一个蓝牙外部适配器：Amitosai MTS-BT5PRO（我认为问题可能出在这个设备上，但奇怪的是在 Ubuntu 20.04（Focal Fossa）中它工作得很好）。

该服务已启动并正在运行（理论上），但它无法检测新设备，也无法连接到已配对的设备。

证明已检测到设备（Realtek Semiconductor Corp. 蓝牙无线电）：

cd ~
lsusb

输出：

Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

服务似乎正在运行（如图所示）

但是日志抛出两个错误：

错误是：

1. 设置模式失败：不支持（0x0c）
2. 设置模式失败：身份验证失败（0x05）

当我重新启动服务时，出现蓝牙错误：

并且

dmesg | grep -i bluetooth

抛出这个：

cd ~
sudo dmesg |grep -i bluetooth

输出：

你知道可能是什么错误吗？

如果您认为是加密狗本身的问题，您能给我推荐一款与 Ubuntu 22.04 兼容的吗？

我尝试了这里发布的许多解决方案，但没有一个有效。

Answer 1

检查笔记本电脑的 BIOS/UEFI 设置中是否启用了蓝牙选项。这些设置控制您笔记本电脑的硬件，如果此处禁用蓝牙，您正在运行的任何操作系统都不会检测到它。

要访问 BIOS/UEFI 设置，请重新启动笔记本电脑并在初始启动过程中按相应的键（通常是 F2、F12、DEL 或 ESC）。进入 BIOS/UEFI 设置后，查找与蓝牙相关的选项并确保其已启用。保存所有更改并重新启动系统。
