Torne Wuff 2eb0142587 New USB charging system, part 2 - "Force" charging mode 
Enable support for the "force" mode of USB charging. This should work on Gigabeat S and Nano2g (and any other future target which has a RB usb stack and supports charging) - if a host connection is not detected within 10 seconds of USB insertion, assume that the connected device is an AC charger and charge anyway, if the user has specified "force" as the mode.
