Problem with Android ADK

Hello,

I'm working on a project using Android ADK with mbed LPC1768. The code is using AndroidAccessory library from Giles Barton-Owen, but I'm having an issue with the USB connection between Nexus 7 and mbed. When connected, Android detects the mbed as an accessory normally. But on the mbed side, I got like this

I'm not sure why this is happening. I have a couple 10 kOhms pulldown resistors on D+/- pins as similar with Giles Barton-Owen's etch-a-sketch example project.

Could anyone help me?

Let me know if I need to explain more or else.

In my case, LPC1768 connect with Nexus 4, interfaceDesc-> interfaceNumber is "1". This means "Number of interfaces supported by this configuration" is one.

But here it's a "0", which means no usable interface.
