这是一台配备 BCM43602 (14e4:43ba) 的全新 XPS 15 9550，我运行的是 Ubuntu 16.04 LTS。当我尝试使用标准蓝牙管理器时，它会搜索并找到一个具有 MAC 的设备（但不显示名称），但“下一个”框呈灰色。我还尝试使用 Blueman 配对设备，但失败了。我尝试信任它然后配对它，但失败了。不知道该怎么办。
有问题的蓝牙设备是 Microsoft Sculpt Comfort Mouse，它可以在我的另一台 Ubuntu 笔记本电脑上运行。
如果我需要提供更多信息，请告诉我。我通常熟悉 Linux，但对内核模块/驱动程序有点困惑。

我有同样的问题，你可以在线安装失败的固件文件
[ 3.352116] bluetooth hci0: Direct firmware load for brcm/BCM-0a5c-6410.hcd failed with error -2
[ 3.352118] Bluetooth: hci0: BCM: Patch brcm/BCM-0a5c-6410.hcd not found
下载自https://www.dropbox.com/s/8goc4omhnzxij93/BCM-0a5c-6410.hcd?dl=0缺失的固件并创建一个像 /lib/firmware/brcm/BCM-0a5c-6410.hcd 这样的文件（所有这些都是来自https://bbs.archlinux.org/viewtopic.php?id=204739和http://ubuntuforums.org/showthread.php?t=2317843）
更新： 另一个版本（v481）可能效果更好：http://ubuntuforums.org/attachment.php?attachmentid=269987&d=1467804097，您还需要将文件放入 /lib/firmware/brcm/BCM-0a5c-6410.hcd
