Query: Two player mode: still a mystery

I received two of these as a gift this Christmas. I plugged in the adapters and the computer recognized them with no problem. However, when they are plugged in simultaneously only input from the first controller is recognized. I have tried testing this through multiple emulators with the same effect. I also swapped controllers around (both function in the first player port), swapped adapters, and also swapped USB ports. I have a message out to the seller asking for a solution since the product description clearly states "Get 2 adapters to challenge your friends to multiplayer games." The controller that does get recognized works well so far, but I do notice that the down button doesn't hold down constantly (which is cumbersome in games such as mario 3 where you have to hold down consistently for certain objectives).I'll update the product review as I receive more details on the simultaneous controls.
