Player one can log into COD MW multiplayer but when player 2 tries to join game crashes

I have the exact same problem and I found out that my problem was related to having a hub hooked up. Once I took the USB hub out everything worked flawlessly.

Edit: I was using a 2.0 USB hub and it just crashes as soon as anyone tries to log in at all besides the first player. I tried this again with a USB 3.0 hub and it allowed me to sign in one player it on the hub the first time and crashed when the second
hub player joined. then on the second attempt it crashed when the first hug player tried to join. After removing the hub again, everything went back to working flawlessly with 2 and 3 players. This is 100% for sure an issue with hubs and using wired controllers.

Two Worlds had a multi-player, Two Worlds 2 had Multiplayer you tell me Bethesda cant do better? Call of duty MW, MW2 and Black OPs have Multiplayer and their single player is good.

Mention not those filthy abominations here! It's a matter of opinion as to whether COD's single-player is actually "good", I mean, I enjoyed MW 1 and 2, but to compare that to an ES game...

It happens with all accounts, whoever the second player is, just doesn't work. Doesn't matter who opens the game, I've tried logging in with both controllers on and signed in, tried with just one signed in and then another logging in. Its like the "Press A to Join" for the second player doesn't work. The second player can navigate menus and log in just not join, ever!

I have liked every cod since mw and battlefield since bad company 2.

On 360 cod was the better game, being restricted to 12v12 on maps designed for alot more players didn't really feel like as much fun as cod. Now with battlefield 4 having 64 players this game is just outstanding and so much more entertaining than cod. Although
the fact that ghosts multiplayer is the worst for a long time doesn't help either.

We can invite each other but unable to join and it usually says unable to join player or in some cases the game crashes for the person who tries to join.
