Name: Atheros AR3012 Bluetooth
I'll keep it simple:
This device does NOT work under Linux ATM, I've tried, trust me, I've really tried. What's even worse, it will cause the Bluetooth Manager in Gnome (and its clones: Unity, Mint...) to behave erratically when you plug a Bluetooth Dongle, that is, sometimes works sometimes doesn't.
The best solution I've found is to tell udev to completely ignore this device, so the USB Dongle can work. Add the following line to an udev rule file: (i.e, sudo vim /etc/udev/rules.d/disable-integrated-bluetooth.rules)
ATTR{idVendor}=="0930", ATTR{idProduct}=="021c", RUN+="/bin/sh -c 'echo 0 > /sys$DEVPATH/authorized'"
And then reload the udev rules, and trigger a change (to avoid rebooting):
sudo udevadm control --reload-rules; sudo udevadm trigger
