Does the phone get power from the Due, or nothing? How do you power the Due?
I think it might be a power problem because my Desire S doesn't connect (only charge) when I'm powering the Due over computer USB while charging another phone from the same USB hub.
Another power problem: the USB host port doesn't seem to power up at all when I'm running the Due on 12V external power. Is there a call I need to make to enable the USB host power?
And it gets better: while the host port appears to be dead, the programming port is powered; I can charge my phone over it! It's not supposed to power the programming port, right?
