I have a Panasonic SC-AKX58 Stereo System that, following a power outage, will only display "INSERT USB B" when powered on and no buttons/controls function. Unable to do the system memory reset suggested in the user manual because no buttons function.

"INSERT USB B" seems to indicate that the unit is expecting a USB stick to be inserted in the USB B socket with firmware on it. I guess the originally installed firmware has become corrupted and requires re-installing via USB.

Does anyone have firmware for the AKX58 or the very similar AKX38 or AKX78?
