我有一台连接到电视的“媒体内容”计算机，我用它来播放电影、音乐和玩游戏。
最近我想通过主板提供的蓝牙使用我的 Wii 和 PS3 操纵杆中的任一个或两个。起初我的 PC 似乎能够检测到 PS3 操纵杆，但无法将它们配对。我甚至能够配对 PS3 操纵杆并查看我触发的各种操作，但当我关闭程序时，设备会取消配对。
我尝试了各种方法，但最终系统还是无法正常工作……
现在，当我开始新会话时，小时附近的蓝牙图标没有显示。我可以启动蓝牙应用程序，但未检测到任何设备。我可能在按照modprobe操作指南中的说明操作驱动程序时弄乱了。
sudo lspci | grep -i blue没有显示任何内容。lsusb
主板是 GIGABYTE GA-Z87N-WIFI，蓝牙曾经工作过。
我使用 Ubuntu 16.04。
我该如何解决这个问题？
这里有一些输出：

答案1
TL;DR：关闭、断开电源、喝杯咖啡并重新启动。
我遇到过类似的问题，我的女朋友将她的手机插入我插入 PC 进行数据传输的 USB 电缆。突然间，我的蓝牙耳机停止工作，所有蓝牙活动都停止了。我搜索了内核日志，发现了与您类似的日志

然后我发现这帖子告诉我不要重新启动，而是关闭，断开电源，让冷凝器清空，然后重新连接. 这样做了，然后轰隆隆：

我正在运行
07:00.0 Network controller: Intel Corporation Wireless 7260 (rev 6b)
设备与 Hackintosh 兼容，但实际上一直切换到 Debian。
答案2
我遇到了完全相同的问题。然后，我进行了内核更新和旧内核 grub 启动等等……所有操作。但都不起作用。
但 pascalwhoop 的答案非常有效。
只需关闭
sudo shutdown -h now
拔掉所有线缆，如电源、显示器 HDMI、USB、UTP Cat5.e 等。然后插上并启动系统。
现在它运行得非常好。
由于 SOF 声誉不佳，不允许发表评论，因此我在这里回答了：)
答案3
安装后我遇到了类似的问题华硕得到我的Xbox One 控制器在 Ubuntu 上通过蓝牙工作。它工作得很好，两天后控制器就不再出现了。
多次重启并搜索可能的驱动程序问题，但无济于事。晚上关闭并再次打开也没用。
最后，拔掉电源插头然后重新启动就成功了。
