I'm trying to use a gamepad under linux (kernel is 4.16.10) and I don't seem to get any input events out of it.

The device, a fake xbox 360 controller, seems to be detected as dmesg seems to report:

#dmesg when pluging in controller

I tried with both evdev and joystick drivers:

Yet, I'm unable to get any input events neither with jstest nor evtest (both as root and non-root). Same with xboxdrv btw.

usbmon gets datas only when pluging in and pluging out the controller. Nothing is reported when buttons are pressed.

But evdev detects sereral possible events:

# evtest

(sorry but txt versions are indigest)

Does anyone has any idea or lead to find a solution to this problem?

Thanks,

If you don't get any USB traffic when pressing buttons, something on the hardware isn't working properly.

Either the hardware is broken, or it needs to be properly initialized during the phase when it announces itself as SHANWAN PS3/PC, or possibly in the incarnation as Microsoft X-Box 360 pad it expects initialization commands by the Windows driver which the Linux driver doesn't supply.

Next step would be to connect it to a computer with the proper Windows driver, see if it works there. If no, return it; if yes, sniff the USB traffic (there are Windows tools for this, google) to find out how it should be initialized.

Edit

I still don't understand the mess with the two devices (and didn't have time to look at it in detail). However, one can see that under Windows, the following exchange takes place, before key events are sent:

In:  01 03 02

Out: 01 03 02

In:  02 03 00

Out:

In:  03 03 03

Out: 

In:  08 03 00

Out: 

Under Linux, only the first line appears; there never is an answer. This could be the missing initialisation (or something else).

While looking at that, I found that xpad is the kernel driver which translates the HID events to input events, I can't see from your dmesg extract if it gets loaded. In doube, check with lsmod. (I couldn't find those sequences during a quick check of the source, though).

There also seems to be a userspace library, see e.g. here, which seems to work better than the kernel driver, so this is also worth a try.

I have the same problem, but I managed to identify the initialization sequence of the Windows driver, and based on that I wrote a python script that sends the necessary codes to the device.

This is the script, you must run it with sudo: pyusb-test.py
