Apparently with Android 2.3.4 and 3.1 one can now access USB accessories.
I have a Ardupilot Mega (based on Arduino) board with a USB cable connected to my laptop, and I can connect to it using a simple serial communications program over COM7 and 115,200 baud. This allows me into the command-line interface, and I can issue commands and get logs.
Is it possible to write an Android app that will communicate over USB to my Ardupilot Mega board?
I've seen many similar threads, but most of them were pre-USB host.
