Nice. So you'll only need a special cable do be able go charge and
usb-host at the same time?
As this cable is a custom one, might be an interesting addition to the
openmoko store that was being discussed on some other thread, so
hardware-challenged people like me can purchase it.

On Wed,
I think this cable must be included in the basic
packaging!!!( well in the advance packaging at last)
If you can plug at time in dc power and usb periphals
whith a usb hub and a keyboard (it can be bluetooth
or usb!!) you can convert in few seconds a mobile
phone in a mini ultraportable

Currently the pump that provides 5V for the external device is enabled
whenever we are in host mode. I don't know what that thing will do if
we provide 5V externally too, probably it will be okay but it needs testing.
You wrote currently. Does that mean with a software change we

So we must do the test to find out where we are.
Interesting stuff. The test result may also vary based on whether the
external voltage is a little higher or lower than what comes out of
the pump.

This was on the list of accessories from the beginning, wasn't it? ;-)

thanks joerg
I've tried to write this up as succinctly as I can.

In the end this means: the 47k ID-R should be in the Y-adapter, and you may
use arbitrary usb-chargers (1A) with it for quick-charge. However the
I think this is a very good observation.
If you want to connect a neo to some usb device(s) for long periods of
time it would be very important to be able to charge it (otherwise it
will just run dry very fast).
Anyone know if you can?

Hey
My neo can run in host mode at the same time it's charging, using a Y
cable or a hardware hack (*).
Can this still be done with freerunner? It will provide power to a usb
slave so it may not be prepared to get juice in at the same time.
