How to access usb port with Android 3.0 sdk

I heard that Android 3.0 sdk is having support for USB Host. I want to read / write data on USB port of Android device using android app. This app will send data to a sensor device connected to usb port of android tablet. Is there any sample code or example available for USB read write ?

If you plan to write commercial apps then forget about rooting. IOIO library allows you to write to USB port (see this link). Although designed to support IOIO board specifically, this lib can be used to send commands through USB.

Try the MissleLauncher example at http://developer.android.com/resources/samples/USB/MissileLauncher/index.html.

Implements very simple async transfer of data. Clear, concise code.

solution:

1) get access to the USB port

2) get programmatic access so that you can use API's from within Java

NOTE: you will need root access to make this happen
