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

Some more info and external references can be found in RHBZ:
