MacBook Pro 13 2009 no hdd no USB


i have a MacBook Pro 13" from 2009 with following defect, the MacBook doesn’t recognize any Drive on USB port and also no internal SATA or ODD. No function at all, the voltage on SATA is there with 5V and also the HDD is running, but not recognizing in the system. There is no water damage or else. Just change the Keyboard and after this I have this failure. Maybe someone have any idea or the same problem.
