How to tell if an Android device has Open Accessory Mode

Question

Does anyone know how to check for this? I just bought a Samsung Galaxy Tab 2 (7\" version running Android 4.0.3) with the intention of using it to connect to my Arduino Mega ADK

Answer 1

Add Galaxy Nexus to the list.

Nexus S ICS 4.0.4 works, 4.0.3 is broken.

Make sure power is sufficient - at least Nexus S will flake out and intermittently stop seeing the ADK board if the board + phone tandem is powered from a USB hub.
