Neither keyboard or gamepad is working – stuck at welcome screen

[ulfjonas]

Hello!

I cant get past the welcome screen in emulation station. Neither my keyboard or my gamepad is working. 1 gamepad is detected but I cant use it or configure it.

I have a Rpi Model B running the lateset Retropie, 3.2.1. A hp usb-keyboard and a SNES usb-gamepad.

What PSU do you have ? Does it help if you have only one of the devices connected ?

[petrockblog]

And you are definitely holding down a button on one of the devices? (obvious question, but just to check).

No, it doesn’t change anything if I just use one of them.one time I entered the config but then I couldn’t do anything. It said to press up button but I couldn’t.

One time I succesfully pressed f4 and that time the keyboard worked.

I have tried different psu’s. Two different iphone/ipad chargers and the tvs usb. Nothing changed.

Yes, I am holding down a button.

Sounds like a problem with your setup. if you press f4, and drop to a terminal (you will need to press another key) can you type on the keyboard ?

are you using any hub or anything ? Which controller are you using ? Can you confirm the controller works on another machine

When you say you tried different chargers, did you use the same USB cable or have tried different cables?

[ulfjonas]

The keyboard worked just fine the one time I entered the terminal.

No hub.

Same cable only different chargers. Do you think that the pi gets to little amps to run both the keyboard and the controll?

I’m using a cheap snes-usb-controller that is working on my computer.

Could be a power issue yep – Please try another USB power cable, combined with the ipad charger (which should be 2.1a or so).

I had a rubbish cable from china that gave me similar problems. Got a new one and it solved the issue. Also if you have a rainbow in the top right corner of your screen in definitely is a power issue.

Ok! I’ii try another cable and see if it solves the problem.

Thanks for the help!

I’ve tried some things today.

I found my ipad charger, 2,2A, and tried it with the old cable. Retropie starts but when emulationstation starts it directly restarts. In the start up i saw something about the usb-cable. Think it said “maybe usb cable is broken”. It had problem finding both the keyboard and the gamepad. Said something about usb failed -71 or something.

Then I tried it with the iphone charger 1A and it started correctly but I couldnt configure the gamepad.

Any thoughts?

get a new cable, or decent 2amp psu
