Ubuntu 13.10 安装在带有 ASUS Z87 Pro 主板的机器上，该主板附带其内置的“Wi-Fi GO！”无线网络，该无线网络基于 Qualcomm Atheros AR9462 无线网络适配器（包括 WiFi + 蓝牙 4 功能）。
我可以打开蓝牙，扫描设备，但找不到任何东西。旁边还有另一台运行 Windows 的机器，它可以看到我设置的可见设备。
我在我的计算机上安装了 Windows，一旦驱动程序加载完成，我就可以毫无问题地使用蓝牙，因此硬件运行正常。
我承认我对 Atheros AR9462 的工作原理有点困惑，因为 WiFi 似乎在 PCI 总线上，而蓝牙在 USB 上 - 至少，这是我所了解到的。

有什么建议吗？
答案1
14.04 中的蓝牙问题尚未解决，因为它更多的是受支持的驱动程序问题，而不是错误。我甚至考虑编译最新的 Bluez 版本，因为我认为它不是驱动程序。但在测试内核 3.14 和 3.15 后，我发现蓝牙正在运行。我的智能手机检测到了华硕蓝牙，反之亦然。
因此从内核 3.14.x 开始，华硕 Z87-Pro 将获得蓝牙支持
如果你确实想尝试一下（请注意，这可能会产生其他问题。目前对我来说没有，但如果我遇到一个，我会跳到 3.13）：你需要去http://kernel.ubuntu.com/~kernel-ppa/mainline/并搜索 3.14 内核甚至 3.15。由于我使用的是 14.04 64 位版本，因此我使用了以下命令：
有关 3.14 版以来网络变化的更多信息，请参阅：内核新手
下载完所需的 DEB 包后（在相应的文件夹中查找您实际需要的包）。然后将它们全部放在同一个文件夹中，并在该文件夹中运行以下命令：
sudo dpkg -i *.deb
这将安装该文件夹中找到的每个 DEB 包。下图显示 Ubuntu 14.04 可以正确使用蓝牙（使用 3.14 及以上版本的任何内核）。Ubuntu 14.10 开箱即可使用：
图片使用的是三星耳机 (HM1200)。可以正常使用 Hangouts、Skype、VLC 和听音乐。
