Ubuntu 15.04 – 蓝牙 – 未找到适配器 – Dell Precision M4800
发布Ubuntu 15.04升级后，我发现蓝牙在我的机器上被禁用了。 我继续并启用相同的function，从那时起，我的Blueman蓝牙管理器无法帮助我设置我的设备。
我的配置细节：
sudo service bluetooth status ：

继Jerry的输入之后，问题通过以下dmesg解决了 尾部转储validation

应该很容易

然后检查固件是否加载dmesg | tail 请在评论中发帖或编辑您的问题
echo btusb | sudo tee -a /etc/modules
当你的内核更新时，蓝牙将失败直到你
