I found a legendary bracer item, unidentified. It seems unidentified items are incredibly rare, as this is the first one I have encountered despite being somewhat far in.
It says "press x to identify", but pressing x does not identify it. Is this a bug? Do I need to get further in the game to unlock some identification skill?
This is for the Xbox360. edited in answer to own question you hold down the X and wait for a bar to fill.
