    The firmware was extracted from a Windows 7 32-bit installation
    and converted from 'hex' to 'hcd' for use in Linux.

    The firmware is named "BCM20702A0_001.001.024.0156.0204.hex"
    and is located in "%SYSTEMROOT%\system32\drivers\"
    (md5 d126e6c4e0e669d76c38cf9377f76b7f)
    (sha1 145d1850b2785a953233b409e7ff77786927c7d2)
    
    The same firmware file is also available as a download at
    http://support.ts.fujitsu.com/Download/
    contained in "FTS_WIDCOMMBluetoothSoftware_6309000_1072149.zip"
    
    'hcd' file should be placed at "brcm/BCM20702A0-0489-e031.hcd"
    inside the firmware directory (e.g. "/lib/firmware")
