Arduino ADK - Disable battery charging from ADK?

Projects General Guidance
1

Hi,

I was considering to do an application with Arduino ADK that involved the measurement of the energy drawn by the phone from the battery. Nevertheless I have seen that ADK provides 500mA of energy to charge the battery of the phone, hence interfering with what I want to do. Is it possible to disable this feature (probably not because it is part of the USB standard) or force the phone to stop charging?

Thanks in advance!
Jordi.

this is incredibly related to my topic here http://arduino.cc/forum/index.php/topic,109786.0.html

I think it is impossible to stop the battery charging, due to the fact that there is only one configuration to choose from, and that configuration specifies a 500mA requirement, and you can't establish a connection without selecting a configuration
