I own a Acer Aspire E5-551G. Wi-fi works fine, but Bluetooth is not working?. I already tried several methods to solve this problem, but nothing has worked for me. Here are some outputs which were demanded by various approaches to solving my problem.

After rebooting the Bluetooth didn't work anymore. I found out that I had to add btusb
to /etc/modules
. But when I now reboot I got a Bluetooth-entries in my Gnome Control Panel (this thing at the top-right corner) which won't work and will only redirect me to my network-settings. After enabling the Bluetooth in my settings a 2nd Bluetooth-entry appears which works.

uname -a
as I think I can make it work
