There was a problem that I can not handle. A week ago, when connected via the "big picture" to adequately manage the Steam controller. Now the button "A" does not work (or not work as "A"). With some other buttons have the same problem. Just before the button displayed as "A" Y "and so on. Now they can be displayed as" 03 "," 04 ".
Has anyone encountered a similar problem, and whether there are ways to solve it?
Just threw the controller settings to the default. It did not help.
