Hello kenban,
Can you verify the power pin layout for the 5.4VDC and 5VDC the input on the USB sync/charge cable? This pin layout was posted by other Aximsite member under the title "X50V pin layout?". It said Pin 1-4 are for 5.4v and pin 21 for 5v. Following is the link to the pin layout picture. Thanks,
