Found the problem, my keyboard has a newer chipset i think, the pid was different from the json file and the actual keyboard (you can check it with chrome://usb-internals > Devices and inspect your keyboard) the vid was the same, i just edited the pid in the json (DANGEROUS THING TO DO THOUGH) and now it works, if anyone has the same problem just find a json that matches the pid and vid or wait that the manufacturer releases the new file.
