You would need to build routes specifying controllers first then have (:any) rule last.

Code:

$route['controller1/(:any)]' = 'controller1/$1';
$route['controller2/(:any)]' = 'controller2/$2';
//etc or could do this dynamically by reading directory then loop to create routes

//Add last
$route['(:any)'] = 'user/$1'; //route any uri not above to the user controller.
