Acabei de ter um numpad USB para usar com o meu Xubuntu 15.04
O pad tem um botão "Num lock" com o LED ligado / desligado quando pressionado, mas as teclas numéricas (0-9) ou sinal (. + - / *, ENTER, TAB) não produzem nada visível na tela.
Eu preparei algumas informações para ajudar a investigar. Dispositivo 009 em lsusb :
