'lsmod' gives me Modules listed with Size and Used-by info.
mac80211 --- 154215 --- 1---ath9k
ath9k_common --- 1448--- 1--- ath9k
ath9k_hw --- 248527--- 2--- ath9k,ath9k_common
ath--- 10270--- 2--- ath9k,ath9k_hw
cfg80211 --- 98209--- 3--- ath9k,mac80211,ath

I guess that the entries with "ath" are the modules for Atheros but I'm not able
to find out if any of them support the Bluetooth device which is listed by 'lspci':

07:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

How can I find out what is needed?
