If you want USB charging, the cheapest option is to buy the Luxos U headlight. Riv, Peter White, and several European sellers carry it. I'm very happy with the Luxos U, I have them on two bikes and convinced my girlfriend's father to get one.
Otherwise, there are plenty of add-on USB chargers. They're a less-integrated but possibly more robust solution. This article is a good resource. http://www.cyclingabout.com/list-of-hub-dynamo-power-supplies-for-usb-devices/ A separate USB device allows you to use any headlight. The Luxos U has a very wide beam but it has lots of reflector artifacts (noticeable bars in the beam). They don't bother me but they do bother some. Also, if you get the Luxos U, follow Riv's recommendations to mount it high and centrally (to get the most out of its massive beam) and to protect the backside from water coming off the tire. On my Riv Road 650b, I mounted it to the front of a Mark's rack, shielded by a Treetop rando bag. On my Foundry Auger, I mounted it to the handlebar, shielded by the front fender. Congratulations on your new dynamo wheel!
