[ale] USB host mode on android tablet

[Steven A. DuChene]

Also I note that plugging a USB keyboard into an Android device does not seem to work. From what little I have read it is because USB host mode is not enabled in early versions of Android. It is possible to somehow either add this functionality via replacement kernel modules or perhaps even rebuild a new/different kernel for one of these devices to enable this? I have looked at some of the dmesg output from one of my el cheap'o tablets and I see some things happening there when I plug in a keyboard but not enough apparently. It looked like the appropriate modules for USB devices were loading so it seems like the hardware is there but not completely functional.

Does anyone know if it would be possible to reconfig an Android tablet to NOT have a full desktop interface with icons and things and instead have it boot up to the display of a single application?

Does that mean it would be possible to run a standard Java application without the load of a full JVM? Is all compiled Java code end up being 8-bit bytecode that could be directly run on this CPU?
