I own an Acer C720 and set the same in /boot/device.hints. After boot it
says in dmesg:

$ dmesg | grep ath
ath0: <Atheros AR946x/AR948x> mem 0xe0400000-0xe047ffff at device 0.0 on pci1
ath0: RX status length: 48
ath0: RX buffer size: 4096
ath0: TX descriptor length: 128
ath0: TX status length: 36
ath0: TX buffers per descriptor: 4
ath0: ath_edma_setup_rxfifo: type=0, FIFO depth = 16 entries
ath0: ath_edma_setup_rxfifo: type=1, FIFO depth = 128 entries
ath0: Enabling WB222 BTCOEX
...

But I don't know how to further enable any BT device. The above
hcccontrol just says:

# hccontrol inquiry
hccontrol: Could not create socket: Address family not supported by protocol family

What in addition I should load or do to get BT working?
Thanks
