ubuntu 14.04蓝牙BCM43142没有发现（tx超时）
我正在浏览很多关于这个问题的post，虽然我找不到一个单一的答案。
问题：无法发现\检测其他蓝牙节点。

请注意，我们正在谈论一个组合。 即它是物理网络接口卡上的wifi和蓝牙设备。
可以请一眼就这个问题说清楚：
- 怎么了？
- 有没有软件解决方案？ （我知道我可以买不同的硬件）
更新：我遵循pilot6链接，并为这两个架构做了描述的步骤。 即32位和64位。 我已关闭计算机，但问题仍未解决。 随附更多信息，如果需要任何其他信息，请告诉我。

我不确定，虽然看起来固件没有加载：

从底部看到4行 – Driver=btusb 。 因此，我不确定复制固件是否有帮助。

您需要先安装固件。 可以使用这个答案来完成。
但看起来内核3.13.0-59有很多错误。 其中包括无法加载固件。
我建议将内核升级到3.19。 它可以通过在终端中运行来完成
sudo apt-get install linux-generic-lts-vivid
并重新启动。
