未找到蓝牙适配器 HP 250 g2 Ubuntu 14.04 lts

未找到蓝牙适配器 HP 250 g2 Ubuntu 14.04 lts

启动时出现两条消息 -

Bluetooth: error in firmware loading err = -110, len = 440, size = 4076

Bluetooth : Loading patch file failed

蓝牙设置中显示“未找到蓝牙适配器”

我从其他人的帖子中尝试过这个

这是最近重新安装后蓝牙再次工作时 lspci 等的结果...现在又不工作了。

答案1

解决此问题的一个可能方法是,您可能在 BIOS 或 EFI 中禁用了蓝牙。如果这不是问题所在;您应该做的是通过启动另一个发行版或操作系统来确定这是否是硬件故障,您可以在其中测试蓝牙在该实例中是否正常工作。如果碰巧这不是硬件故障,那么您应该在 Launchpad 中报告错误

https://help.ubuntu.com/community/ReportingBugs

这对开源社区来说是一个很大的帮助。

答案2

我有类似的蓝牙硬件。联想 G50-70 配有 Atheros 蓝牙卡,运行 Kubuntu 14.04。从 lsusb:

Bus 002 Device 007: ID 0cf3:3004 Atheros Communications, Inc.

我也遇到了加载失败错误=-110。

我发现/lib/firmware/ath3k-1.fwkubuntu 附带的 不起作用。附带的文件的 MD5 和为1211fa34c09e10ba48381586b7c3883d ath3k-1.fw。您需要的文件具有 MD524cfee59a24f336dfae838a0de6445a0 ath3k-1.fw 和,可以从 中提取linux-firmware_1.79_all.deb

这解决了我四五个月前的问题。今天想再次使用蓝牙,但它都坏了,这些步骤不再能解决问题。我认为这是一个新内核,因为我第一次修复了它,我现在处于:

3.13.0-43-generic #72-Ubuntu SMP Mon Dec 8 19:35:06 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

我知道当我修复它时它是一个新的内核,但我的意思是,我认为这个变化是导致蓝牙再次被杀死的原因。

因此,经过两天的绞尽脑汁,反复检查我的步骤,我安装了一个 BIOS 更新,原始更新是 2013 年 12 月的,新的是 2014 年 8 月的(我想,要么是 8 月 11 日,要么是 11 月 8 日……您自己选择!)我登录准备继续战斗,瞧,我的程序栏中出现了一个时髦的 B 标志,单击它会显示我所在地区的 BT 设备列表!结果它也会切断我的 WiFi 连接,上次我修复问题时没有发生这种情况!
