I'm working on doing a cable to connect to the N800 mini usb port, an external USB battery powered charger and to a female usb port.

Anyone have the schematics on such a configuration. It would save the need for a powered usb hub.

Basically it would be mini usb connector, male USB connector and female USB connector Y cable. I would get an off the shelve one but I want to make it compact and light.

I have a Minty Boost charger for the power supply:

Essentially its a cable to create a powered usb port for the N800.
