xbox360 controllers receiver  doesn't light up anymore, also doesn't make the sound of usb when connected to pc, it seems the receiver is dead(the green light doesn't light up), it wasn't dead, but after the windows update the controller went crazy, so I tried some things that I saw on youtube and Disconnected the recever
look, doesn't even recognize unknown device usb
one more thing, my receiver and controller is (MIcrosoft) original/official, not from China


outros dispositivos means "other devices"
dispositivo desconhecido means "unknown device"

as u can see the receiver is plugged, but the sign "?" still there

somebody could help me ?
sorry for my bad English
