I think that Windows doesn't turn on power for a USB device until a driver recognizes it and OKs full power; I've run into this with other battery chargers in the past, and with other combinations of devices. Even though I have 6 different devices with USB in my living room, I can only charge my iPhone from one of them. EDIT: This is opposed to Linux and Mac OS, which seem to be happy to provide plenty of power as soon as the device handshakes - I regularly charge my iPhone off of my ReadyNAS without any problems.
