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

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.
