Hopefully this will be ported to the Nexus S. I am so excited. I will finally get expandable memory on the phone. Will the USB port be able to power a low powered usb device like a flash drive?
Is there a chance that this will work without having an external power source?
Maybe. In theory the S3C controller has the appropriate functionality, but in practice it might not work (for example there might be missing connections inside the PCB, etc.)
