Here's how to get it working:
Grab the firmware:
$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.gitCopy the ath3k firmware to /lib/firmware:
$ sudo cp linux-firmware/ath3k-1.fw /lib/firmwareGrab compat-wireless:
$ wget http://www.orbit-lab.org/kernel/compat-wireless-2.6-stable/v2.6.39/compat-wireless-2.6.39-rc1-3-s.tar.bz2
Compile compat-wirless:
$ tar jxfv http://www.orbit-lab.org/kernel/compat-wireless-2.6-stable/v2.6.39/compat-wireless-2.6.39-rc1-3-s.tar.bz2
$ cd compat-wireless-2.6.39-rc1-3-s
$ make
$ sudo make install
Plug in your USB dongle, and see if it works:
$ sudo hciconfigYou should see something like:
