Bug 3277

Summary: Upgrade from SDL 2.0.3 to 2.0.4: The key you just pressed is not recognized by SDL.
Product: SDL Reporter: firemass
Component: joystickAssignee: Sam Lantinga <slouken>
Status: ASSIGNED --- QA Contact: Sam Lantinga <slouken>
Severity: minor    
Priority: P2 CC: buzz
Version: 2.0.4   
Hardware: ARM   
OS: Linux   

Description firemass 2016-02-29 09:02:40 UTC 
My System:
Raspberry Pi 2 with Rasbian, Kernel 4.1.17
Gamepad: Wii U Pro Controller connected via xwiimote (https://github.com/dvdhrm/xwiimote) and Bluetooth
Keyboard: Small Bluetooth keyboard

I have RetroPie working on this system which is a compilation of several emulators for the Raspberry Pi. These emulators and their frontend make much use of SDL.

As long I had installed SDL 2.0.3 I had no problems.
After the installation of SDL 2.0.4 some days ago I get several of these error messages when I start any of the emulators:

INFO: The key you just pressed is not recognized by SDL. To help get this fixed, please report this to the SDL mailing list sdl@libsdl.org EVDEV KeyCode 545
INFO: The key you just pressed is not recognized by SDL. To help get this fixed, please report this to the SDL mailing list sdl@libsdl.org EVDEV KeyCode 305

My gamepad does not work anymore if I use sdl2 in RetroArch (http://www.libretro.com/). My key bindings got messed up. Using udev instead my gamepad works again. But those errormessages still remain.

What can I do to solve this? Is there is anything I can do to take a deeper look into this please let me know.

I have bisected this to https://hg.libsdl.org/SDL/rev/6c86d3216f6a

I can confirm it breaks ps3 and the wii U pro and possibly other controllers. Had to roll back to 2.0.3 on RetroPie due to problems, but will revert this and do a custom 2.0.4 for our project.

I hope this can be looked into - without the patch we had no major problems before, and PS3 controllers worked.
