이것은 BCM43602(14e4:43ba)를 갖춘 새로운 XPS 15 9550이며 Ubuntu 16.04 LTS를 실행하고 있습니다. 표준 블루투스 관리자를 사용하려고 하면 MAC이 있는 장치를 검색하고 찾았지만(이름은 표시하지 않음) "다음" 상자가 회색으로 표시됩니다. Blueman을 사용하여 장치 페어링도 시도했지만 실패했습니다. 믿고 페어링해봤는데 실패했습니다. 무엇을 해야할지 잘 모르겠습니다.
문제의 블루투스 장치는 Microsoft Sculpt Comfort Mouse이며, 다른 Ubuntu 노트북에서도 작동합니다.
더 많은 정보를 제공해야 한다면 알려주시기 바랍니다. 나는 일반적으로 Linux를 사용할 수 있지만 커널 모듈/드라이버는 다소 혼란스럽습니다.

저도 같은 문제가 있었습니다. 실패한 펌웨어 파일을 온라인으로 설치할 수 있습니다.

업데이트: 다른 버전(v481)이 더 잘 작동할 수 있습니다.http://ubuntuforums.org/attachment.php?attachmentid=269987&d=1467804097, 또한 파일을 /lib/firmware/brcm/BCM-0a5c-6410.hcd에 넣어야 합니다.
