ubuntu 15.04 - bluetooth not detecting nor being detected - acer aspire

Question

I've been trying to get the issue solved elsewhere but nothing worked out, installed all possible packages but still nothing. I got a Acer Aspire V13, just installed Ubuntu 15.04, bluetooth icon is displayed but neither recognizes nor is recognized anywhere. I've also tried with a different bluetooth manager and still nothing. Needless to say, I'm quite of a newbie to Ubuntu.

Output of lslsb:

Bus 001 Device 002: ID 04ca:300d Lite-On Technology Corp. Atheros AR3012 Bluetooth

Thanks a lot in advance!

sudo apt-get install linux-firmware linux-headers-generic build-essential
wget https://www.dropbox.com/s/xu80svavlazttaf/bluetooth-3.19.tar.gz
tar xpvf bluetooth-3.19.tar.gz
cd bluetooth
cp /boot/config-$(uname -r) .config
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo cp ath3k.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/

And see if it works after a reboot, if it doesn't show the results of dmesg | grep -i firmware and dmesg | grep -i bluetooth

Your bluetooth chip is not supported by the kernel yet.

Here is the Bug report. You can vote there that the bug affects you too. There is a temporary solution there. But it is too technical for a common user.

I sent a few patches upstream to add some of these devices, which have been applied. But in this case also some firmware should be added. I wrote to kernel maintainers, but it will take some time to fix it.
