如果您需要任何特定命令的输出，请在评论中告诉我。
答案1
你的蓝牙芯片是Qualcomm Atheros AR3012，它是由ath3k.ko内核模块驱动的。您的lsmod输出表明模块实际上已加载。
但该模块还需要一个固件文件/lib/firmware/ath3k-1.fw，该文件包含在软件包中firmware-atheros。该软件包位于non-freeDebian 软件包存储库的 部分。如果您还没有安装它，请安装它。如果您在最喜欢的包管理工具中没有看到firmware-atheros可用的包，则可能需要首先启用非免费存储库部分。
（注意：这里的“非免费”是指“没有可用的源代码，因此不是完全免费的软件”。这并不意味着您需要付费。）
要启用非自由存储库，请/etc/apt/sources.list以 root 身份编辑该文件。你会看到类似这样的一行：
deb http://deb.debian.org/debian buster main
non-free只需在末尾添加关键字即可：
deb http://deb.debian.org/debian buster main non-free
然后以 root 身份运行apt update，并再次尝试您最喜欢的包管理实用程序。现在该firmware-atheros软件包应该可以安装了。
