WLAN:
0d:00.0 Network controller [0280]: Atheros Communications Inc. AR9462 Wireless
Network Adapter [168c:0034] (rev 01)
Subsystem: Lite-On Communications Inc Device [11ad:6621]
Kernel driver in use: ath9k
Kernel modules: ath9k
lsusb (BT-device identified as):
Bus 002 Device 003: ID 04ca:3006 Lite-On Technology Corp.
iProduct value is 2, so it must be a AR3012 based chipset for BT (see
attachment).
I have adjusted in accordance with
http://wireless.kernel.org/en/users/Drivers/ath3k the source codefor
ath3k.c and btusb.c
See attachment for further informations and Terminal output.
Used CW snapshots and firmware:
compat-wireless-2012-07-03
linux-firmware-HEAD-e0836e6
Options for ath9k are set in /etc/modprobe.d/ath9k.conf: options ath9k
btcoex_enable=1
First try with this patch to add the needed ID an blacklist this device
for btusb:
