Comment(by andy):

 I can see the USB insertion at +12370s in the dmesg log, there is no USB
 removal subsequently. And in the register dump, I can see the MBC
 recognizes that USB power is present, but is says that USB power is not
 "OK". OK would have meant that USB power is >50mV above the current
 battery level.

 So it does seem something is wrong with your charger, it sends out
 something less than ~4.3V when it should be a great source of 5.0VDC.
