Joypad config selecting wrong device?

[AndreasDavour]

Hi I've tried multiple emulation wrappers, and emulationstation is really great! I do have one issue, though.

When I try to config my controller, it seems to be able to detect my buttons, but only one joystick axis.

Running lsof to see which device the program is accessing I see this:

$ lsof | grep emulation | grep dev
emulation 20547 ante mem CHR 226,1 9412 /dev/dri/card1
emulation 20547 ante mem REG 253,1 65960 2098118 /usr/lib64/libudev.so.1.6.1
emulation 20547 ante 0u CHR 136,19 0t0 22 /dev/pts/19
emulation 20547 ante 1u CHR 136,19 0t0 22 /dev/pts/19
emulation 20547 ante 2u CHR 136,19 0t0 22 /dev/pts/19
emulation 20547 ante 6u CHR 226,1 0t0 9412 /dev/dri/card1
emulation 20547 ante 8r CHR 13,77 0t0 844024 /dev/input/event13

This makes me think that it has grabbed the wrong device. I know that the device it should use is /dev/input/js0 as that one seem to work better if I specify it explicitly in some emulators.

How about some option to select which device to use, either as a command line switch/config file option or within emulationstation itself?

Thanks.
