I've read all the posts but i am confused a bit.
I've tested my USB Host shield (noname) with USB Host library v2 board_qc fw:

Android device is Samsung Galaxy Ace with android 2.3.4 (and i have copied usb-related jar, xml files and modified permissions file in order to add missing adk support files in samsung firmware).
It seems that it should work, but no - android device does not recognize device as Accessory and does not send broadcast intent that accessory is attached (i have uploaded ArduinoBlinkLED fw and installed according android app).
So, what android devices support ADK really and what devices did you use to test?
