Hi!
My laptop (Acer Aspire VN7-591G-77FS) has a combo Atheros
Wireles/Bluetooth card. In the back of the laptop it has a sticker
saying "This device contains WLAN-Bluetooth module QCNFA344".
I'm running kernel 3.19.0-31-generic (Linux Mint 17.2) with
backports-20150903, and the card id recognised as follows

The problem is that bluetooth doesn't work although it seems that it
is being recognised. As it is actually a USB device, I tried to attach
it in a VirtualBox machine running windows 10 which recognised the
device and installed the drivers. After that if I detach it from the
VM, it works ok in linux until a reboot.
I'm guessing that it needs some kind of firmware in order to work. As
it seems to me (based on
https://wireless.wiki.kernel.org/en/users/drivers/ath3k#how_to_tell_ar3011_and_ar3012)
this is an AR3011 device, and so I added it's id in ath3k.c and
btusb.c in a similar way as here:
http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=6eda541d12116b4772baa09d3e8d7b0389df4289
After rebooting, I didn't get any errors in dmesg but the device is
not recognised at all know. Eg rfkill list gives the following
0: acer-wireless: Wireless LAN
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
3: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
It doesn't work any more even if I do the attach to VM trick.
My assumption here is that the provided firmware (ath3k-1.fw) doesn't
work with this particular card. Am I right?
If this is the case, is there any way to extract/dump the firmware or
any other initialization commands that windows is sending to the
device? I used Wireshark in combination with usbmon to capture the
traffic but I cannot make sense of the captured packets.
Any help/suggestion would be highly appreciated.
Thank you in advance,
John Salatas
