This is not a standard function.
Such a project can be done with a microcontroller board. These are examples
of components you might use. http://en.wikipedia.org/wiki/Arduino http://circuitsathome.com/products-p...-0-for-arduino
The purpose of me showing you those, is to show how small the components can be.
There are many details to consider, before such a project would be finished.
The project could be made even more compact than that, but then it would be
a custom project, with much time invested in its completion.
The project can be done with a regular PC computer, one with USB host interface
and RS232 interface. If you have a spare computer, you could write a simple
program to provide the interface, read the USB mass storage device and so on.
