Atheros bluetooth problems

Hello! I have HP netbook with both Windows and Archlinux installed, and experiencing problems with bluetooth. I've read about bluetooth problems on ArchWiki, that for bluetooth to work properly, it has to be turned on in Windows, and it is. However, Arch can't seem to load the driver.
hcitool can't find any bt devices:

dmesg shows errors:

Adapter is found via lsusb:

lsusb | grep -i ath

rfkill doesn't list it:

rfkill list
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

I'm using kernel 3.3.3-1
Could somebody help me with this?

Re: Atheros bluetooth problems

I believe you may be having the same issue as I am.

See this thread: https://bbs.archlinux.org/viewtopic.php?id=126487

It seems when the device is recognised, the vid:pid (from lsusb) is used for the device in the kernel drivers, but then when the firmware is loaded, it changes the pid, hence you do not have a valid device in the kernel drivers.

So while your device is detected correctly, due to the pid change, the device will not work.

There is lots of discussion on the internet regarding this, but I am still waiting for a fix. I did try emailing the bluetooth team on the kernel mailing list, but have not received a reply.

If you are able to find anything further, it would be appreciated.

Cheers.

Re: Atheros bluetooth problems

FWIW for people who see this while searching, I had the exact same problems and resolved it simply by installing the package bluez-firmware.
