我的蓝牙无法打开。我经常遇到这个问题，我只需重新启动即可，但现在它让我很烦。我有蓝牙，但仍然无法检测到，我必须重新启动。
我尝试检查蓝牙的使用状态systemctl status bluetooth，结果是
bluetooth.service - Bluetooth service

我参考了这篇文章 ->未找到蓝牙 - 插入适配器以使用蓝牙 - Ubuntu 18.04.1 LTS
但对我不起作用。我运行了rfkill list all，结果是
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
我注意到这个问题是在我遇到 USB 问题时出现的。在启动 PC 时会显示错误110，然后我插入和拔出 USB，然后会显示错误71并开始启动。也许它已连接，但这种情况只会发生 10 次中的 4 次，所以是的。
我知道这篇文章很长，所以我就到此结束了。除了那些愚蠢的重启之外，还有其他解决方案吗？
这是输出lspci -knn | grep Net -A3; lsusb; suro dmesg | grep -i blue
