Just for the record: I'd like to add that, in my case at least, I don't have any other peripherals connected.
I am having the same issue! Can't believe this went out of beta with this issue.
I have a Kensington Slimblade Trackball and a Logitech keyboard. Keyboard seems to work alright and sometimes the mouse works, but my gun is pointed to the sky and I cannot pan. I can fire, I can reload, but in the menus I can't clikc on the buttons.
Guys, don't know if someone suggested that earlier, but disable Origin in-game. With the Origin overlay I could navigate menus in-game just fine, but in the game itself everything was dead. Turned off the overlay and bam, it works. The overlay hooks into the game nad "steals" mouse and keyboard inputs. Nice "feature" EA.
Unfortunately, I've already tried that. While I did notice that, with everything else being unresponsive, I could still access Origin with Shift-F1, disabling it didn't prove to be a solution for my real problem. And besides being abel to open it, Origin in-game is unresponsive as well (for example, I wouldn't even be able to close it again).
