The firmware was extracted from a Windows 8.1 64-bit installation
and converted from 'hex' to 'hcd' for use in Linux.

Under Windows it also identifies itself as BCM20702A0,
but the firmware is named "BCM20702A1_001.002.014.1315.1356.hex"
and is located in "%SYSTEMROOT%\system32\drivers\"
(md5 67cf6bfdae61c4bb819a66da984f7913)
(sha1 5f74cc6a9a3bf19ee0f8c3d01e4be34c609b188f)

The same firmware file is also available as a download at
http://www.asrock.com/mb/Intel/Z87E-ITX/?cat=Download&os=All
marked as "Bluetooth driver ver:12.0.0.7820"

'hcd' file should be placed at "brcm/BCM20702A0-13d3-3404.hcd"
inside the firmware directory (e.g. "/lib/firmware")
