I don't think any armed ship can be flat out useless against a sub. But really old destroyers could be rather ineffective if they lacked the agility. The old destroyers that the UK got from the USA, for example, were regarded by the admiralty as not particularly suited for ASW duty. They were fast but had a very high turning radius, by WW2 destroyer standards, which made a sub's task of getting out of the way a lot easier.
Well, I suppose the whole IJN was utterly useless against subs in the beginning of WW2. Though not through a fault of the ships themselves, but rather because the Japanese thought nobody can dive too far and set the depth charges to explode at a rather shallow depth. So the explosion tended to be nowhere NEAR the US sub they were hunting. Come to think of it, I'm not sure why they had that misconception, since their own subs could dive deeper than what they set their depth charges for.
Japan also had poor sonar and not all their ships were fitted.
'One of Our Submarines' by Edward Young has a good account of submarine warfare in the Far East. It's Young's war memoire and the best first hand account of sub warfare I have read.
