I have a problem. I use Win Xp SP3 and, the controller worked well for three days and now, when i plug it on pc: "usb device not recognized". I already installed and uninstalled the xbox driver' for Win XP, uninstalled the usb driver from mobo, but the problem continues. I know the controller is working, when i plug it on my father's pc (an old P4 with XP SP3), it's automatically detected as "controller".
