I recently bought an APC UPB10 portable USB battery -- see
When the Neo gets its kernel support for USB host mode, I'm going to try
to wire it up as an auxiliary power source for USB peripherals like
Look at this picture:

Right now I haven't figured out how it's internally wired -- whether the
data lines on those two sockets go anywhere. I'd like to wire them

mini-B cable with the power lines disconnected.
