I am running the ADK demo app tweaked for Android 3.1, using the ASUS Eee Pad Transformer tablet and an ADK board, built as described in Get Started With Android ADK (LINUX).
I seem to be having the same symptoms as described in Stack Overflow question How can I get the ADK DemoKit example working on a Google I/O Galaxy Tab 10.1?. It could be the transformer does not support the ADK yet (as per the Galaxy tab), but is it possible to get the Transformer working somehow?
