The USB-Bus Device is unpowered. It uses external Power for Battery
Charging.
So try to make your own 5V supply.

If you do decide to go this route (building a 5V supply), you can power
it from
the neo's 3.7V battery with an LM2621 chip from national semiconductor. It
claims to have 87% efficiency converting 3.6V to 5V with a 500 mA load. Does
anyone know what kind of current a USB WLAN card draws?
The chip also has a "shut-down" mode in which it draws very little current.
I may try this in the near future, since I am interested in using other USB
devices.
Another option is a battery powered USB hub, like this one:

Anybody know if that'll work? I'm just starting on this project...
