emulationstation crashed when connect two joysticks

[dumisky]

Pi Model or other hardware:pi 4
Power Supply used: 5v 3a
RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest):4.7.1
Built From: Pre made SD Image on RetroPie website
USB Devices connected:2 joysticks
Controller used:2 joysticks
Error messages received:Emulation Station Crashed!

When I connect two usb controllers, ES will crash when the system starts up.

When I connect one usb controller, everything is ok.

I have tried to burn the image with a different tf card, and I have tried to download the latest official image again, and I am using the original image without any modification.
I also changed the power supply, and now I use a 5V 3A power supply.

This is the joystick I use：

please help me!

@dumisky Don't you need one "joystick control board" per joystick? Are you plugging them both into the same board?

@iandaemon
Thanks for reply
Yes, I have two boards, two sets of buttons, two USB cables.
ES crashed when I plug in two usb cables at the same time.

The crash may occur if the joystick disconnects before it gets fully initialized. Since your configuration works with one board connected, but not two, I suspect it might be related to insufficient power provided by the Pi that disconnects the 2nd (or 1st joystick) randomly.

Looks in the system's log while having both boards connected and see if you see any connects/disconnects event. Run

sudo dmesg -c

before plugging any controller, then run

dmesg -w

and plug both controllers one by one. Post any error messages showing up on the screen.

I conducted some tests in the past two days:

I installed ubuntu 20 on a J1900(Intel x86) and installed retropie.
When I try to connect two controllers,ES crashed.

Then when installing windows 10 on J1900, everything is OK when connecting two controllers.

So, could it be a driver problem?

Hard to say without any logs to help diagnose what makes EmulationStation crash. Did you have to install any driver to make the controllers work ? I don't think they've needed any drivers on Linux at least.
