Just to give you feedback on this bug, I'm now using Linux Mint 18.2 (which is based on Ubuntu 16.04 LTS). I followed André von Kugland's directions at Ask Ubuntu (https://askubuntu.com/a/964350/560233) and made my Bluetooth adapter work. His laptop has the same Bluetooth adapter (ID 04ca:3014) as mine, so he helped me. Here is what I did.
I installed the HWE (Hardware Enablement) kernel using $ sudo apt-get install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04 (https://wiki.ubuntu.com/Kernel/LTSEnablementStack) Kugland noticed that the Bluetooth adapter was being disconnected after loading the acer_wmi kernel module. So he said to blacklist it: $ sudo nano /etc/modprobe.d/btconfig.conf blacklist acer_wmi Also, he suggested adding to that same file the following line, which, according to the documentation of the ath9k kernel module (https://wireless.wiki.kernel.org/en/users/Drivers/ath9k), reduces interference between Wi-Fi and Bluetooth adapters: options ath9k btcoex_enable=1 bt_ant_diversity=1 So that: $ cat /etc/modprobe.d/btconfig.conf blacklist acer_wmi options ath9k btcoex_enable=1 bt_ant_diversity=1 Finally, I updated the initramfs: $ sudo update-initramfs -c -k all And rebooted the system. When it came back, the built-in Bluetooth adapter was working. Now, I can use my laptop's built-in Bluetooth and my USB dongle (0a12:0001) is free to be used on another computer. I'm not sure that contributed to the final result, but before I have installed the linux-firmware package: $ sudo apt-get install linux-firmware Also, not sure this is a part of the solution, I installed all the updates available using apt-get update and apt-get dist-upgrade. I believe this is a good habit. I'm going to add as much diagnostic information as I can about my setup, just in case anyone else in the future needs to make that Bluetooth adapter work.

Also, the acer-wireless interface does not appear anymore (because I blocked the acer_wmi module). Thank you all!
