Waterproofing micro USB B port on waterproof project box


I am in need of a way to waterproof a micro usb B port (or water-resist since the port will only at most be rained on) of a microcontroller (the Adafruit HUZZAH)  in order to access the USB port (for charging and reprogramming) without having to open the case. I am open to any ideas that would keep the box watertight and not having a wire hang out of the box anywhere. I've searched for a bit on google and found nothing that will help me. If anyone has any idea or experience with this issue some advice would be greatly appreciated!


Maybe something as simple as putting a balloon over it? Then you just uncover it when you need to access the port.

I would simply use a case with a cover for the port, but I guess that would be too obvious for a solution....
Even a glued on top from a soda bottle would do, same for a piece of PCV pipe with end cap or two lego bricks....
