蓝牙不工作- Atheros AR3011

Question

蓝牙不适用于Ubuntu17.10.1。我是linux新手，我不知道该怎么做。我试过rfkill列表，所有的东西都没锁。数独表明它是无人认领的。这是司机的问题吗？这个设备的驱动程序是lib/固件，它是ath3k-1.fw。怎么解决这个问题？

我试了16.04，但还是不起作用。dmesg \ grep ath

我刚才在Ubuntu20.04上遇到了这个问题，并且能够通过安装linux模块来解决这个问题--我的内核是额外的。重新启动之后，蓝牙适配器就开始工作了。

sudo apt install linux-modules-extra-$(uname -r)

即使在内核升级的情况下，您也可以通过安装linux泛型来确保这一点始终被安装。

sudo apt install linux-generic
