Using just a USB charger the red and green lights stay on longer (maybe a full second) and then go out. Tried the DefuSeDemo tool again and did an upgrade and it said it was successful, but the version number did not change when I went to the Web IDE. Can you provide some brief step by step instructions on using the DFU tool? I have a feeling I'm just missing a step somewhere and it is uploading the firmware to the wrong place or something.
