I got my two new Dualshock 4 controllers (original, bought from authorized Sony Reseller, not online from eBay :).
Got them paired and connected pretty easily (once I figured the initial blinking wasn’t the “fast” mode and I had to press the two buttons quite long to enter pairing mode…)
Anyway, they connected and paired just great and I can control the menus with them… kinda. The controls repeat like CRAZY! Usually left and right repeat twice (so it changes two menuitems to selected direction instead of one), but up and down repeat so fast I cannot actually navigate the menus. If I manage to hit the main Settings-menu, hitting “Input” is pretty much impossible. If I just lightly tap down, the whole menu scrolls once through and I’m back at the first menu item (drivers).
/storage/joypads/udev is empty, so there shouldn’t even be anything that would mess up the controllers.
I also disconnected any old controllers that I used before (one wired Xbox360 and a a few wireless Xbox360 controllers with the genuine MS dongle for the controllers.), which worked just fine.
This might be a bit too confusingly described, but ask then
