Pierre,
no, it shouldn't be hard. If you figure out where the USB device is mounted (it'll be in /dev/usb1 or /deb/kb1 or some such, use lsusb to figure out) you can read the raw data in in Python, it's very easy. You just open it as a regular file and read() your data and add them to Pygame's event queue. You'd just do this every frame before processing events. I'm not sure if Pygame is eating the keyboard input, though, so you might not be able to get access to it while Pygame is running. I only do Windows development so that is why I am being vague, I don't know the exact way to solve this. I assume you have already tested a regular keyboard and using the numeric keypad and that works on the ARM platform, right? It's just this specific device that's not working?

Lets say I want to write my own code to get keyboad event.
Is this something I need to be expert to do that (wich I'm not) ?
What language would you use to do that ?
I will look onto usb dev, but I need options. This wireless keyboard is
critical for our project.

Thanks for your support
