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.
