Некоторые примеры вызовов (srry для расстройства и комментария кода, возможно, документация в один прекрасный день):

echo time()."\n";
$ub = new ubuntuOne;
/* The first time you made the commented calls, then you save the authorization 
 * to a file. Once you have it on a file, you load it every time from there */
//$ub->requestAuthentification('sombra2eternity@gmail.com','*****','st');
//$ub->registerToken('sombra2eternity@gmail.com');
//print_r($ub->auth);
//$ub->saveAuth($GLOBALS['userPath'].'db/uOne.protected');
$ub->loadAuth($GLOBALS['userPath'].'db/uOne.protected');
//$ub->registerToken('sombra2eternity@gmail.com');
$ub->u1_getRoot();
//$ub->u1_file_exists('/~/Ubuntu One/non_exists/');
echo "\n";
$ub->u1_listFolder('/~/Ubuntu One/');
echo "\n";
$ub->u1_createFolder('new folder','/~/Ubuntu One/');

Удачи, надеюсь, это поможет
