I have a Seeeduino ADK board. When I use the Android ADK firmware which consists of USB_Host_Shield and AndroidAccessory I can compile a sketch and an Android App that will complete the handshake but then won’t exchange data.
I tried updating to Circuit@Home’s version of USB_Host_Shield_2.0 library so that I could try out his demo code but I get: “OSCOKIRQ failed to assert” when calling Usb.Init().
This makes me wonder - is the Seeeduino ADK board compatible with the Circuits@Home USB Host 2.0 library? Or are there changes required?
Here’s a link to that library:

I’m going to go back to the Android ADK firmware version of USB_Host_Shield and see if I can’t get that working.
Any help or pointers will be greatly received!
