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-page/arduino-shields/usb-host-shield-2-0-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.

Without knowing what's on the other end (at the USB end) and assuming
you are trying to connect a USB device to an RS-232 port (not the other
way around), maybe one of these will work (found through the simple
Google search http://www.google.com/search?q=+usb++rs232+converter):

Pumped through Google's translator (English -> French):

Sans savoir ce qu'il ya sur l'autre extrémité (à l'extrémité USB) et en
supposant que vous essayez de connecter un périphérique USB à un port
RS-232 (pas l'inverse), peut-être un de ces fonctionnera (trouvée par la
simple recherche sur Google http://www.google.com/search?q =% +% 2Busb
2Brs232 + convertisseur).
