Isn't it exciting how fast software moves? Good news is that Chrome has updated it's gamepad interface to match the latest standards. The bad news... these are breaking changes that will require us to refactor our implementation to get it to work.
For the software geeks that want to look at all of the grimy details, you can track the changes from Chromiums Issue List.
I'll fast track the updates and post when the gamepad is up and running again.

UPDATE 2014-05-26 : 7pm PST
The patched gamepad code had been added to the master and 2.5-rc1 branches in github. If you are having trouble with the gamepad on any build of the cockpit software because Chrome has auto-updated, you can grab the file from here and copy over the file on the same spot on whatever version of cockpit you are using today.
