這是帶有 BCM43602 (14e4:43ba) 的新 XPS 15 9550，我運行的是 Ubuntu 16.04 LTS。當我嘗試使用標準藍牙管理器時，它會搜尋並找到具有 MAC 的裝置（但不顯示名稱），但「下一個」方塊呈現灰色。我也嘗試使用 Blueman 來配對設備，但失敗了。我嘗試信任它然後配對它，但失敗了。不知道該怎麼辦。
有問題的藍牙裝置是 Microsoft Sculpt Comfort Mouse，它可以在我的另一台 Ubuntu 筆記型電腦上運行。
如果我需要提供更多信息，請告訴我。我通常能夠使用 Linux，但核心模組/驅動程式有點困惑。

我也遇到了同樣的問題，你可以在線上安裝失敗的韌體文件
[ 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
下載自https://www.dropbox.com/s/8goc4omhnzxij93/BCM-0a5c-6410.hcd?dl=0缺少的韌體並創建一個類似 /lib/firmware/brcm/BCM-0a5c-6410.hcd 的檔案（所有這些建議來自https://bbs.archlinux.org/viewtopic.php?id=204739和http://ubuntuforums.org/showthread.php?t=2317843）
更新： 另一個版本（v481）可能工作得更好：http://ubuntuforums.org/attachment.php?attachmentid=269987&d=1467804097，您還需要將檔案放入 /lib/firmware/brcm/BCM-0a5c-6410.hcd
