For my girlfriend this is not a problem since we bought it yesterday. But my problems are different. I can charge it no problem but can't have it connected to the computer because the screen connect window opens & closes really fast. I have tested it on 2 other computer and am able to connect to it easily.
Tried 4 different port, no change. But yesterday on setting up my GF new Kobo (on the first connect it didn't have a problem (unplugging it after seems to have loosen her connector). So it seems like it just my Kobo and my computer not liking each other.
