xboxパッドをUSB化して使いたいのですが，
以下のように誤認識します．

uhub3: Microsoft Internet Keyboard Pro, class 9/0, rev 1.10/5.00, addr 2
uhub3: 3 ports with 2 removable, bus powered

どうすればゲームパッドとして使えますか？

# usbdevs -v
Controller /dev/usb2:
addr 1: full speed, self powered, config 1, OHCI root hub(0x0000), SiS(0x0000), rev 1.00
port 1 addr 2: full speed, power 64 mA, config 1, Internet Keyboard Pro(0x001c), Microsoft(0x045e), rev 5.00
