Hi, After reading many topics regarding how to configure 2 gamepad in the forum, I feel the need to post my own issue here.

• I got latest recalbox version (17.12.02), I'm using raspberry 3 model b.

• I'm using 2 arcade joystick from Quimat, using 2 USB controller, with same configuration

The 2 gamepads are working like a charm in recalbox, but not inside the emulator (neogeo, megadrive, MAME, tested many of them), the buttons in the second player are broken. (but up/down/left/down work), but not (x/y/a/b)

I've followed this link:
https://forum.recalbox.com/topic/4630/mapped-2p-buttons-don-t-behave-correctly

It seems a problem with the USB port, and it proposes adding a custom property in cmdline.txt usbhid.quirks=xxxxx

This is my lsusb output:

lsusb

Bus 001 Device 005: ID 0079:0006
Bus 001 Device 004: ID 0079:0006
Bus 001 Device 003: ID 0424:ec00
Bus 001 Device 002: ID 0424:9514
Bus 001 Device 001: ID 1d6b:0002

Does it help? Device 004 and Device005 got the same ID.

Anyway, I tried to modify the cmdline.txt and configure again the 2 gamepads, but the problem is still there (Probably I'm not doing it correctly )

I' got the recalbox-support logs, I'll try to attach in the post.

it would be nice to know what else can I do to test my 2 gamepads working in the raspberry using latest version of recalbox.

(I reproduced the same issue in retropie)

Any help would be very very welcomed.
