Description (partial)

The internal USB state machine had an Invalid state that was not accompanied by any alarm. Since the state was Invalid, no write was attempted and hence a USB-WRITE-FAIL alarm was also not raised. 

This means the silent failure of USB, without any indication to the user.

USB state being present and Invalid leads to silent failure of the USB.
