I thought I'd chime in. With the latest development versions, something seems to be broken with rumble. The stable version works flawlessly.
Try enabling 'background input,' and try switching the order of 'Motor R' and 'Motor L' for player 1. Why this worked on my end, I have no idea - but I had to both of those things, or no rumble for any of the players.
I especially hate the 'background input' setting, but that's the price I pay to have rumble with the latest development versions.
