Comment 44 for bug 1189721

I'm on 13.10 64 bit and it worked for me. I packaged it into an installable dkms and attached it. Maybe this will help...

If you've never built a kernel or kernel module before:
sudo apt-get build-dep linux-image-$(uname -r)

Then download attachment and run:
mv rtbth-3.9.3.dkms.tar.gz /usr/src
cd /usr/src
sudo tar -zxvf rtbth-3.9.3.dkms.tar.gz
sudo dkms install -m rtbth -v 3.9.3
sudo modprobe rtbth

To remove:
sudo dkms remove rtbth/3.9.3 --all
