I'm trying to make Costume Quest (game by Double Fine) use either of my gamepads and according to developer's support all I need to do is add SDL2 config line to SDLGamepad.config file, however, I can't find the correct values for UUID. None of the values provided by lsusb, dmesg or udevadm match examples (below) where UUID is 32 chars long (first column):

030000006d0400001ec2000020200000,Logitech Rumble Gamepad F510(Linux),a:b0,b:b1,x:b2,y:b3,start:b7,back:b6,guide:b8,leftstick:b9,rightstick:b10,leftshoulder:b4,rightshoulder:b5,dpup:h0.1,dpleft:h0.8,dpdown:h0.4,dpright:h0.2,leftx:a0,lefty:a1,rightx:a3,righty:a4,lefttrigger:a2,righttrigger:a5,

What should I use there? My config file entries don't work:

0003:0E8F:0012.0016,GreenAsia Inc. USB Wireless 2.4GHz Gamepad,a:b1,b:b2,y:b3,x:b0,start:b9,guide:b13,back:b8,leftstick:b10,rightstick:b11,leftshoulder:b4,rightshoulder:b5,dpup:h0.1,dpleft:h0.8,dpdown:h0.4,dpright:h0.2,leftx:a0,lefty:a1,rightx:a2,righty:a3,lefttrigger:b6,righttrigger:b7,

lsusb output:

==== edit ====

In case someone came here only for this, this is my GreenAsia Inc. config, working on Linux using xpad:

030000008f0e00001200000010010000,GreenAsia Inc.,a:b2,b:b1,y:b0,x:b3,start:b9,guide:,back:b8,leftstick:b10,rightstick:b11,leftshoulder:b6,rightshoulder:b7,dpup:h0.1,dpleft:h0.8,dpdown:h0.4,dpright:h0.2,leftx:a0,lefty:a1,rightx:a2,righty:a3,lefttrigger:b4,righttrigger:b5,

Stumbled across this - here's a ruby script that doesn't require any compiler knowhow: http://bazaar.launchpad.net/~taktaktaktaktaktaktaktaktaktak/+junk/joystickguid/view/head:/joystickguid.rb

  • Yes, it should be - at least, it matches the sdl2 id for my gamepads. – Tak Jul 13 '14 at 9:39
  • It works and it's bit simpler than previously accepted solution so... yeah, sorry Grumbel. :) – cprn Jul 20 '16 at 20:58

The GUID is an SDL2 specific ID, there is no direct way to get it with system tool. The GUID is build by squishing the bus, vendor, product and version numbers into a single value, you can see it here:


One way to get it is by reading it from SDL. The following program does that, compile it with:

gcc -o sdl2-joystick sdl2-joystick.c `pkg-config --libs --cflags sdl2`

Save the following as sdl2-joystick.c:

#include <SDL.h>

int main()

  int num_joysticks = SDL_NumJoysticks();
  int i;
  for(i = 0; i < num_joysticks; ++i)
    SDL_Joystick* js = SDL_JoystickOpen(i);
    if (js)
      SDL_JoystickGUID guid = SDL_JoystickGetGUID(js);
      char guid_str[1024];
      SDL_JoystickGetGUIDString(guid, guid_str, sizeof(guid_str));
      const char* name = SDL_JoystickName(js);

      int num_axes = SDL_JoystickNumAxes(js);
      int num_buttons = SDL_JoystickNumButtons(js);
      int num_hats = SDL_JoystickNumHats(js);
      int num_balls = SDL_JoystickNumBalls(js);

      printf("%s \"%s\" axes:%d buttons:%d hats:%d balls:%d\n", 
             guid_str, name,
             num_axes, num_buttons, num_hats, num_balls);


  return 0;
  • Thanks, it works and of course you're right about UUID being an SDL2 specific value. Devs from DF should consider including config wizard in their games instead of "outsourcing" this task to the end user. – cprn Nov 18 '13 at 21:08

Have you tried Steams Big Picture Mode and configure your controller there? As far as I understand Steam will automatically generate the SDL2 config that way and hand it over to the game.

    This is what I ended up doing, however, it would be awesome to know how to get this value on system level. – cprn Oct 29 '13 at 18:52
