Android USB Accessory Communication with Linux System

Question

I am trying to setup a Nexus One phone to communicate with an application running on a Linux tablet.

On the phone side of things, the Nexus One is Android 2.3.4 so it has the USB accessory library on it. And I have created an application Android following the instructions on http://developer.android.com/guide/topics/usb/accessory.html. I have verified that the Android application works by plugging it into the Microchip Accessory Development Starter kit and connecting to it.

On the Linux side of things, I have configured it to register the Nexus device with the usbserial module and create a ttyUSB0 device when the phone is plugged in. I have verified my application reads and writes to ttyUSB0 correctly. I did this by connecting it to a serial port on another computer and watching data come in through minicom.

Unfortunately The Android developer website does not cover any configuration that host devices (in my case, my Linux tablet) need to perform. In other words, what protocol does the Linux heed to follow to communicate with the phone?

Answer 1

This is not possible. After further research it is not possible to communicate with the Android device using serial USB communication. To communicate with Android applications through Linux use the libusb-1.x library.
