After updating to yosemite, my logitech f310 controller doesn't seem to work. some of the buttons do, but most don't. on mavericks, it worked nearly flawlessly with most games, not even having to set anything up. Now, for instance, trying to continue my Guacamelee game after upgrading and the only buttons that work are the d-pad. i can get the action buttons to work ONLY if i'm pressing a direction on the d-pad. i.e. i have to be holding left to jump. if i just press jump (or any other button) it doesn't do anything. tested rogue legacy, arkham asylum and portal and they're all doing the same thing. i've never installed any drivers, and logitech doesn't provide any. as far as I know it works from the native HID driver in os x. is this happening to anyone else? perhaps with other controllers? anyone have a clue as to why or what to do? thanks!
