Using Piwik Device Detector without the rest.

// I figured it out.  Pretty easy.  Grab a copy of master and make a few mods.

// At the top of DeviceDetector.php and in this order:

require_once (dirname(__FILE__).'/spyc.php');

require_once (dirname(__FILE__).'/Cache/Cache.php');
require_once (dirname(__FILE__).'/Cache/StaticCache.php');

require_once (dirname(__FILE__).'/Parser/ParserAbstract.php');

require_once (dirname(__FILE__).'/Parser/Bot.php');
require_once (dirname(__FILE__).'/Parser/OperatingSystem.php');
require_once (dirname(__FILE__).'/Parser/VendorFragment.php');

require_once (dirname(__FILE__).'/Parser/Client/ClientParserAbstract.php');
require_once (dirname(__FILE__).'/Parser/Device/DeviceParserAbstract.php');

// Add as the first line of addClientParser():
        require_once (dirname(__FILE__).'/Parser/Client/'.$parser.'.php');

// Add as the first line of addDeviceParser():
        require_once (dirname(__FILE__).'/Parser/Device/'.$parser.'.php');

// You'll also have to grab a copy of spyc.php - google it - easy to find.

// That's it.  Works awesome.  Faster than anything else.
