华硕笔记本电脑 ubuntu 22.04 上未找到蓝牙

我在我的笔记本电脑（Vivobook-ASUSLaptop-X1502ZA-R1502ZA）上安装了 ubuntu 22.04。当我想从设置中打开蓝牙时，我收到了“未找到蓝牙”消息。我尝试了不同的解决方案，但一无所获。我运行sudo service bluetooth status并得到：

○ bluetooth.service - Bluetooth service
    Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor pre>
    Active: inactive (dead)
      Docs: man:bluetoothd(8)

此外，这是的输出lspci -knn | grep Net -A3; lsusb; sudo dmesg | grep -i blue：

更新

当我运行以下命令时：

sudo modprobe btusb
sudo rmmod btusb
sudo systemctl start Bluetooth

获取这些输出sudo dmesg | grep -i blue

我已经遇到同样的问题好几个星期了。对我有用的方法是完全关闭计算机，甚至拔掉电源线一段时间然后再打开。基于此帖子：

对于您来说，因为它是一台笔记本电脑，您可能需要取出电池。
