Mouse not detected

Libretro Lakka
#1

Hi.

I’m making an adapter for the original Guncon to USB. Using an arduino.

The arduino is programed to work as a USB HID Absolute mouse.

It’s working in windows and on a ubuntu inside a VM.

But I can’t get it to work in Lakka.

dmesg output

Retroarch detects no udev device.

Need to edit any file to make it work?

You need to find and change pid/vid to a mouse one so it knows what config to use. Nice project btw :+1:

Got it working on another linux box. There was something bad in the HID descriptor. Running retroarch with crt res. I will share the code later and also will look if it’s possible to make a autoconfig for it.
