Subject: Re: [PATCH] Add support for Atheros AR5B195 combo Mini PCIe cards (AR3011 Bluetooth)

Hi Alexander,

> The AR5B195 Mini PCIe card is made up by an AR9285 Wi-Fi chip and an
> AR3011 Bluetooth chip. The operating procedure of the device, as well
> as the rationale behind the patch is documented in
> https://wireless.wiki.kernel.org/en/users/Drivers/ath3k#ar3011_with_sflash_configurations
> 
> The bluetooth device is exposed to the host as a generic USB device
> (04f2:aff1 Chicony Electronics Co., Ltd, in this case) and requires
> firmware to be uploaded to it, so that it can be re-enumerated as an
> AR3011 device. This translates to adding the Vendor and Product IDs to
> the btusb.c blacklist and to the ath3k.c list of supported devices.
> 
> I made the patch against the source of kernel-3.18.6-200, currently in
> Fedora updates-testing and I've also tested it with a couple of 3.18.5

it looks like that your mail client scrambles up the tabs vs spaces here.
