我已经安装了 Ubuntu 20.04，但蓝牙对我不起作用。但是如果我从 USB 启动它，它可以在实时会话中工作。有人可以帮我吗？

systemctl | grep -i blue 输出：

  sys-devices-pci0000:00-0000:00:14.0-usb1-1\x2d14-1\x2d14:1.0-bluetooth-hci0.device        loaded active     plugged   /sys/devices/pci0000:00/0000:00:14.0/usb1/1-14/1-14:1.0/bluetooth/hci0

dmesg | grep -i blue 输出：

我使用的是 Ubuntu 20.04，我拥有一对 Airpod pro。

Ubuntu 检测到设备但无法配对/设置/连接。我知道这一点，因为当我点击它时，它有一个旋转的标志，就像它试图连接一样，然后它只是返回到默认的“未设置”。

我遵循了这里设置 ControllerMode 的建议，我尝试了“dual”和“le”，但都没有成功。
