As it stands, two of the subs were caught and sunk on 7 December:
No. 20, at the mouth of the harbor, detected and sunk by The Destroyer Ward (DD-139) at 06:37
No. 22, inside the harbor, fired it's torpedos at the Speaplane tender Curtiss (AV-4) and at the Destroyer Monaghan (DD-354) which responded by sinking it at 08:43
So the U.S. Navy was aware of thier presence and any subs lurking after the attack would have been spotted and dealt with quickly.
The mini subs were also used on a similar mission at Sydney Harbor, 29 May 1942 where 5 subs mounted an unsuccessful attack.
