FIXED, take a look at the Launchpad bug!

I have a very peculiar problem on Ubuntu Gnome 14.10 x64. My internal WiFi/Bluetooth adapter gets detected and WiFi works fine. Its Bluetooth functionality also gets detected, all GUI and command line commands seem to work normally (they return no errors) but neither are other Bluetooth devices detected, nor can other devices see my laptop. I suspected it to be an antenna problem (the symptoms are identical), but with Windows 8.1 it works perfectly.

My laptop is an Acer Aspire E3-111-C1LY

  • It works now for me; I submitted the patch to Launchpad.

Can you post the results of lsusb and hciconfig --allas there are some chipsets that are not yet supported correctly

I was able to patch a couple modules so that your bluetooth should work in 14.10 with the 3.16.0-28 64 bit kernel, check with uname -a hopefully it shows x86_64 also

New modules zipped can be found https://www.dropbox.com/s/kufg12cf28eh36l/Ubuntu1410.zip?dl=0 extract them to desktop then in terminal sudo mv /lib/modules/3.16.0-28-generic/kernel/drivers/bluetooth/ath3k.ko /lib/modules/3.16.0-28-generic/kernel/drivers/bluetooth/ath3k.ko.bak

sudo modprobe -r btusb

sudo mv /lib/modules/3.16.0-28-generic/kernel/drivers/bluetooth/btusb.ko /lib/modules/3.16.0-28-generic/kernel/drivers/bluetooth/btusb.ko.bak
cd Desktop
cd Ubuntu1410
sudo cp btusb.ko /lib/modules/3.16.0-28-generic/kernel/drivers/bluetooth/btusb.ko
sudo cp ath3k.ko /lib/modules/3.13.0-39-generic/kernel/drivers/bluetooth/ath3k.ko
sudo apt-get install linux-firmware
sudo modprobe ath3k
sudo modprobe btusb

With any luck it will work as I haven't witnessed the xhci glitch with loading the firmware in 14.10 like it was in 14.04

New edit 1/1/2015, a different method with patched ath3k.c and btusb.c files Edit: download this https://www.dropbox.com/s/ajxndivy4vwgapv/test.zip?dl=0 and extract it to /home so you have a folder named test in home, then in terminal 

sudo apt-get install build-essential
cd test
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make all
sudo modprobe -r ath3k
sudo modprobe -r btusb
sudo mv /lib/modules/$(uname -r)/kernel/drivers/bluetooth/ath3k.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/ath3k.ko.bak
sudo mv /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko.bak
sudo cp ath3k.ko  /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo cp btusb.ko  /lib/modules/$(uname -r)/kernel/drivers/bluetooth/

then Reboot.

  • At first I though Bluetooth was also provided by the AR9565, so I frowned upon your suggestion to run lsusb. Oh was I wrong; I'll go and edit my question.

  • I suspect this device is not supported yet by Ubuntu in 14.10, in terminal enter

    modinfo ath3k | grep -i e078

  • I think I found the corresponding bug in Launchpad. Also, modinfo ath3k | grep -i e078 does not output anything. I'll consider this question moot then and markyou answer as the accepted one. (on a side note, shouldn't ath9k handle this as it's an AR9XXX? Anyway, modinfoing that doesn't yield anything containing e078 either.)

  • Eventually the Ubuntu 14.10 kernel will be patched to support your 0489:e078 as patches have been applied to btusb and ath3k in bluetooth next, you will need to install package linux-firmware so ath3k can load the firmware when it does get support

Try with the below command and install the bluetooth genome again and then check whether you are able to connect to the bluetooth device, 

sudo apt-get install bluetooth blueman bluez-hcidump bluewho python-bluez  bluez-tools

Hope this helps.

  • Thank you; I've already tried installing additional Bluetooth packages from another answer here, but it didn't help. My repos (the default ones) don't have the bluez-hcidump package. The python-bluez and blueman packages were new, I installed them, but as of now it didn't help.
