Which devices do and do not support USB Host mode?

Question

Could someone please provide a comprehensive list of which devices do and do not support USB Host mode out of the box with no rooting, OS rebuilding, or cable hacking required?

Answer 1

"Provide a comprehensive list?" Pretty tall order there, pardner ;)

Nevertheless, support for USB Host Mode is available on Android 3.1 or higher:

http://developer.android.com/guide/topics/usb/host.html

Here's an extremely interesting article about interfacing an Arduino to an Android:

And you can Google for specific Android 3.1++ devices that support USB Host Mode (including, of course, the Xoom tablet)

'Hope that helps
