Linux 下的蓝牙都不能连接多个设备吗?

这个问题首次是在 LegionGo 的 Bazzite 上发现的,
当我连接两个 Pro Controller 时,
其中一个手柄会离线, 连接的手柄状态灯乱闪,
离线的手柄不能重联 (除非重启蓝牙服务).
而后我又在安装了 Pop!_OS 的联想 R9000P 2021 款机器上测试,
这次状态灯不闪了, 但是断连情况还是存在,
只要我连接手柄, 蓝牙鼠标也会断开 (不重启蓝牙服务, 所有断连的设备都不能重新连).
再后 LegionGo 上安装了 ChimeraOS 测试, 结果和第二个测试一样.

附上断连后的部分蓝牙日志

LegionGo 重装系统到 Windows11 后上述蓝牙问题都解决了. 多设备愉快玩耍.

  > 测试结果是  Arch Linux (ChimeraOS) , Ubuntu Linux (Pop!_OS) , Fedora Linux (Bazzite) 
  > 都对蓝牙多设备支持不好

  > Windows 对蓝牙多设备完美支持 (Linux 游戏主机, Linux 专用设备除外)
