Title:
Atheros bluetooth doesn't find the devices
Status in linux-lts-utopic package in Ubuntu:
In Progress
Bug description:
I have a laptop Acer v15 with Qualcom Atheros bluetooth and Logitech
M557 mouse, which worked well initially. Then after disconnecting the
mouse, my bluetooth adapter can't find any bluetooth devices nearby
(I've also tried the Samsung s4).
This bug is reproducable in Elementary OS 0.3, Ubuntu 15.04 and 14.04, Mint 17.1 and 17.
Here are some outputs from terminal:
