Hi Daniel, thanks for your comments. I noted this issue initially with proposed zesty (bluez 5.43-0ubuntu1.1 and 4.10.0-38-generic kernel), and filed this report on zesty with ubuntu-bug.
And then I recalled when I was playing around with proposed xenail (bluez 5.37-0ubuntu5.1 and 4.4.0-98.121 kernel) and it seems that I had the same issue. I need to go back to confirm my memory. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1727147 Title: [Dell Inspiron 20 - 3064] [Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter] [168c:0042] The bluetooth detection is gone with kernel 4.10.0-38-generic on zesty Status in bluez package in Ubuntu: New Status in linux package in Ubuntu: Confirmed Bug description: When testing proposed kernel of zesty Linux 201606-22459 4.10.0-38-generic #42-Ubuntu SMP Tue Oct 10 13:24:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux hciconfig did not output anything.
