USB Gamepad Not Found By SDL2 In Win 8.1 VM?

Hi,

I am having problems with my USB gamepad not being found by SDL2
in a Microsoft Windows 8.1 Pro 64Bit guest VMWare Player virtual machine
under a Kubuntu 14.04 L.T.S. 64Bit host.

The USB gamepad is plugged into a USB 2.0 on my desktop
and Win 8.1 Control Panel correctly shows the gamepad connected and working
but my SDL2 video game does not find the USB gamepad?

How would I fix the above problem?
Thanks!

Could you post the code with which you detect the pads? I bet you are using SDL_GameController and it does not have the mapping. If so try to SDL_JoystickOpen

Code:
//-------------------------------------------------------------------------------------------------
Input::Input(void)

    JoystickDeviceTwo = NULL;

    if (SDL_NumJoysticks() == 0)
    {
        printf("No USB joysticks are plugged in.\n");
    }

            NumberOfJoyAxises[0] = SDL_JoystickNumAxes(JoystickDeviceOne);
            printf("SDL2 Joystick 0 initialized.\n");
        }

        if (SDL_NumJoysticks()>1)
        {
            JoystickDeviceTwo = SDL_JoystickOpen(1);
            NumberOfJoyButtons[1] = SDL_JoystickNumButtons(JoystickDeviceTwo);

            NumberOfJoyAxises[2] = SDL_JoystickNumAxes(JoystickDeviceThree);
            printf("SDL2 Joystick 2 initialized.\n");
        }
    }

    for (int joy = 0; joy < 3; joy++)
    {
        JoyUP[joy] = Axis1;
        JoyDOWN[joy] = Axis1;
        JoyLEFT[joy] = Axis0;
        JoyRIGHT[joy] = Axis0;

        JoyButton2[joy] = Button1;
    }

Oh! I've lost my bet! :P

And in which part of the code it enters? What returns SDL_NumJoysticks()?

What compiler did you use? Maybe try the new Visual Studio Community, that's free even for commercial use for single devs.
