我一直在尝试解决这个问题，我有一台联想 Z50-70 20354
我试过这个解决方案没什么效果
我不知道你需要什么信息所以我发布了这个：
这是该代码的输出：lspci -nnk | grep -iA2 net; lsusb; rfkill list all; dmesg | egrep -i 'blue|firm'
输出：

我能做什么？我尝试删除与蓝牙相关的任何内容并再次安装，但毫无效果。
答案1
经过长达 5 个小时的谷歌搜索，我找到了这个问题的解决方案，感谢 ALEXEY BOGDANOV <3
这里是关联指定易于遵循的教程
但是我没有命名文件，而是BCM.hcd保留了名称，BCM43142A0-105b-e065.hcd因为那正是我需要的文件。
