Try something like
$this->set('customer info',$this->Customer->find('first',array('recursive' =>
-1, 'conditions' => array('id'=>$customerId))));
adding 'recursive' => -1 will only get the customer data..
to get e select list for a customer devices
$this->set('customer
info',$this->Customer->Device->find('list',array('conditions' =>
array('customer_id'=>$customerId))));
