问题描述
我无法再次将 PXC550 连接到英特尔 8265 蓝牙。到目前为止，它已经运行了好几个月，没有任何问题。现在，可能是在进行了一些更新后，它停止工作了。
如果我取消 PXC550 与 Linux Debian (Trixie) 的配对，然后重新配对/信任，它就会起作用（即使重新启动）。但是，如果我关闭笔记本电脑，它将无法再次连接（只有在完成取消配对和再次配对的整个过程后才能连接）。
起初我以为这可能是“新”固件，但在我尝试了旧固件后，问题完全相同。

奇怪的是，即使配对/信任成功后我仍然收到错误，但连接正常：

我的内核版本
Debian 6.10.11-1 (2024-09-22) x86_64 GNU/Linux
蓝牙配置（@debain Trixie）
实际上是/etc/bluetooth/main.conf库存。一些用户报告说成功更改了，ControllerMode但没有任何效果。我尝试了 ControllerMode值 dual、bredr、le。
尝试了一下，/etc/bluetooth/input但没有任何帮助。尝试了以下参数组合：
LEAutoSecurity=true/false，UserspaceHID=true/false
完全没有变化 :/。
有谁知道如何进一步调试它，或者更好地知道如何修复它？
