Are You sure, that Your Y-cable is ok? when I connect device through mine *without* using 3th plug, it act just like normal USB cable. in fact, I don't see any logical reasons, why it shouldn't. In fact, even *with* 3th plug connected to charger, USB connection should be achievable (unless You cross data pins, but why would You on Y-Cable, that's meant for hostmode?). /Estel
