Any company that "guarantees" their controller is compatible with Black Ops 2, can't really be honest. There's no way to know compatibility without playing the game.
Even if a modding company pirates an early release, there is still no guarantee that features will still work in the final release.
With that said, I expect these features to work:
Rapidfire
Dual trigger rapidfire
Akimbo
Burst Firing
Dropshot
Sniper hold breath
Auto sprint
I'm not sure if these will work or not:
Turbo melee
Jitter
