Android with mouse, keyboard and touchpad What should I do to be able to use my USB keyboard and mouse with my Android 2.1 tablet? 

I like the idea of bluetooth, but my tablet doesn't support bluetooth.

Is there some device similar to touchpad that can be used instead of tapping to screen?

thank you for answer
You cannot use a keyboard and/or mouse with android. This is not supported unless you have android 3.1 or later. That is the first version that supports USB Host Mode.

For "normal" USB devices, if your device does not support them, you will probably need a MicroUSB -> USB adapter, or a MiniUSB -> USB adapter.
