(please read)
I can't use Bluetooth with my AR9462 WLAN/BT-Combo.
In the link above, it has been fixed, but not for my Adapter ID/Firmware:
System:
Ubuntu 14.10 utopic 64bit - 3.16.0-24-generic x86_64
lspci -nnk
02:00.0 Network controller [0280]: Qualcomm Atheros AR9462
Wireless Network Adapter [168c:0034] (rev 01)
Subsystem: Lite-On Communications Inc Device [11ad:0802]
Kernel driver in use: ath9k
lsusb (identified Bluetooth Device)
Bus 002 Device 003: ID 04ca:300d Lite-On Technology Corp.
ath9k.conf
options ath9k btcoex_enable=1
The "04ca:300d" ID is not in the Kernel, so i added it via dkms.
I took ath3k.c and btusb.c out of the 3.16.0-24-generic source files
and changed them:

dkms status

My patch works, but just like in the bug report above, a Firmware file is missing:
AthrBT_0x11020100.dfu
I found it neither in linux-firmware (http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/ar3k)
nor elsewhere.
