我有一台装有 Ubuntu 22.04 的 Dell T3500，我的蓝牙无法打开。我查阅了有关此主题的其他问题，但没有一个与我遇到的问题完全相同，即此错误：
"Apr 28 20:45:26 ned-Precision-WorkStation-T3500 bluetoothd[1639]: src/profile.c:register_profile() :1.85 tried to register 00001108-0000-1000-8000-00805f9b34fb which is already regist>

以下是一些终端查询的输出。守护进程似乎正在运行，并且加密狗已被识别。
