Problems while building my arcade with - DragonRise Inc. Generic USB Joystick

@dragu should compare with 2 xinmos. I believe it's normal when a controller handles a single player

As long as they are mapped on separate /dev/input/eventX

[Dragu]

@Substring
I totaly agree with you that 1 controller handles a single player. But here he just forget controller #1. So I think that you should be able to map controller #0 to all possible players, with controller #1 (not existing) should be the same.
If I now define in Retroarch Menu, that Player 1 is not existing, after this he map the controller #0 to Player 2, also in game.

@dragu do your encoders respond on separate events when you try evtest ?

[Dragu]

@Substring
Absolutely

# evtest
No device specified, trying to scan all of /dev/input/event*
Available devices:
/dev/input/event0:      DragonRise Inc.   Generic   USB  Joystick
/dev/input/event1:      DragonRise Inc.   Generic   USB  Joystick
/dev/input/event2:      1byone Keyboard
Select the device event number [0-2]:

and he even dont forget my keyboard

@dragu so it's a pure ra problem

[Dragu]

@Substring
Small chance that they resolve with newer version.

[Substring]

@dragu have you checked their github to see if an issue points at your problem ?

[Dragu]

@Substring
Not yet deep inside. Just find traces everywhere. So I will collect. We have 1.6.9 so that's important also.

[Substring]

@dragu they won't bother with a not up to date RA ...

[Dragu]

@Substring
Perhaps, but the time that this story is trailing over the versions...
Discussion in Retropie : https://github.com/RetroPie/RetroPie-Setup/issues/1798
(The USB Socket toggeling remember Bells phone time with a lot of young ladies and electric plugs )
and in the Retroarch Github I found the following about controllers :
https://github.com/libretro/retroarch-joypad-autoconfig/tree/master/udev

What I cannot find in our version is the definition : input_device_display_name,
this is perhaps a possibility to distinct the twins ?

[Dragu]

@Substring
May be one solution, if not resolved in new version to add usb port number in udev rules ? Like this you would have different device names.

[Substring]

@dragu what a pain
