2 controllers + 1 keyboard

kalgon

Hi,

I have retropie 4.1 with

2 wired XBox 360 gamepads
1 wireless microsoft all-in-one media keyboard

When the keyboard dongle/receiver is not plugged-in, my 2 gamepads are working without problem but as soon as I plug the receiver in, my keyboard takes prcedence over the 2 gamepads (keyboard -> player1, gamepad1 -> player2, gamedpad2 -> player3).

For console games, I don't want the keyboard to become player1.

I found other posts about this problem but, so far, no solution has been working for me.

I already tried the following:

force joypad_index (P1 -> 0, P2 -> 1) in retroarch.cfg
remove all keyboard bindings in retroarch.cfg
force all keyboard bindings to "nul" in retroarch.cfg
plug the keyboard/gamepads in other USB ports

Here are the result of evtest

pi@retropie:/dev/input $ evtest

crw-rw----  1 root input 13, 63 Dec 31 17:17 mice
crw-rw----  1 root input 13, 32 Jan  2 14:04 mouse0

My keyboard is listed as 3 separate events (I suppose keyboard, mousepad and media control?).

From /dev/input, I see that js2 must be my keyboard but when I run jstest js2, pressing keys on my keyboard does not raise any event.

I am really running out of ideas of what the problem could be and how it could be solved.

If anybody has any hints, they would be welcome.

Thanks!

I think RetroPie is recognizing your keyboard as a gamepad. If it's taking up a JS slot, I assume this has to be the case.

My keyboard does not take up a JS slot. In RetroArch, you will notice there is a binding for button, and a binding for key. The button bindings come from JS, the key bindings come from a keyboard.

Your post is a little confusing though, because JS0 is player1 by default, but you say JS2 is your keyboard (3rd player).

I would research and see if you can prevent your keyboard from being picked up as a joystick altogether.

Alternatively, you could research this: http://github.com/meleu/RetroPie-joystick-selection

RetroPie is indeed recognizing 3 controllers.

From jstest, I am sure that js0 and js1 are the controllers. I presume that js2 is the keyboard although no event is displayed when I press buttons in jstest.

I tried the joystick-selection script but that does not fix the problem.

When I launch a (nes/gb) game, notifications about controllers are always showing keyboard first (as #0), then the 2 controllers (as #1 and #2).

I have tested with a dumb wired USB keyboard and I don't have a problem with this one.

@kalgon please post your /opt/retropie/configs/all/retroarch.cfg and a /dev/shm/runcommand.log after launching the game with verbose logging on ghostbin (or something similar).

@meleu In the end, I bought a simple wireless keyboard (without mousepad or media buttons) and it works perfectly. The keyboard I had before (microsoft all-in-one media keyboard) gave too much problems in RetroPie.
