RetroPie detects USB controller but buttons don't work

[nicolasludwig]

@mitu Yes, both devices are plugged. One keyboard (which works on RetroPie) and the gamepad (doesn't work on anything).

Well, the gamepad doesn't appear as an input USB device, so there's little to do to make it work. Try running from the terminal (just to debug):

1. unplug the gamepad
2. run sudo dmesg -c
3. plug back the gamepad (make sure it's correctly plugged in)
4. run dmesg and post the output - if any.

@mitu Sorry man. I unplugged the gamepad and plugged it again, now it appears on the output. I don't know why this happened, but sometimes it happens, even though I haven't touched the USB cable.

The output:

OK, but still, execute the commands I posted previously - this will show which drivers are loaded when the gamepad is detected.

@mitu Right. I did it and this was the output:

Looks like the device is switching its config/identification on the run, first it looks like a PS3 clone, then it disconnects and then identifies itself as an Xbox 360 gamepad.

Try installing the PS3 drivers (one a time, see which one works) - doc pagehere - from the RetroPie-Setup script and see if the gamepad is configured and detected properly.

@mitu I tried both drivers (sixaxis and ps3controller), without success. Nothing happens when I try to config buttons, but still appears 1 gamepad detected.

[mitu]

Based on the provided log, the correct driver should be xpad, but I don't see it handling the controller, even though the Vendor/Product IDS are known to the driver.
Can you check if the xpad driver is installed - in the drivers section of RetroPie-Setup ?

[nicolasludwig]

@mitu Yes, the xpad is installed. I removed it and installed it again. The issue persists.

[mitu]

I don't have any other ideas - I see the controller has a windows driver - maybe it needs a special driver to work, but the driver is only for Windows.

[nicolasludwig]

@mitu Yes, on Windows it works normally. Anyway, thanks for your help. I'll try to find more information all over google.
