That is unfortunate - it seems the surface mount USB connectors just don't hold up well without a case to keep them in place. Particularly since you also had problems with BT, so you can't just hook it up to a power supply and use the bluetooth..
Uhm, is that just the lighting, or are there scorch marks all over the bottom of that Espruino? You should be able to solder without it blackening the board - If those are scorch marks, I think your soldering iron is getting too hot (though I don't know that this is related to any of the issues you've had).
