@ElDeadKennedy@shitposter.club @kaia Yes, you are right. It's a "8bitdo zero 2" https://www.8bitdo.com/zero2/ gamepad. It has multiple mode (keyboard, switch, xbox, generic gamepad). Bluetooth on Linux catch the keyboard mode, and the generic gamepad.
I could grab the event on Linux with evtest, while in keyboard mode. So, I remapped the keys with this method https://www.davidrevoy.com/article989/how-to-customise-a-usb-numeric-keypad-under-gnulinux , it's a good little pad to get on my other hand while drawing, especially when I'm taking weird position
@kaia @ElDeadKennedy@shitposter.club Yes, good little device. I'm happy about it. The battery is good enough to paint during 3 or 4 days, and it charges in two or three hour with a micro usb cable. It goes 'sleep' after three minute i think, but start button reconnect it almost immediately. So, it is useful.
