This might prove to be a problem.

They might still let you know which provider they bought from.

If you know of some u-boot board configs that were successfully used for 
this device, and if the board config has USB support enabled but USB 
storage support disabled, then you *might* have a chance of adding USB 
storage. Can you list these configs that were used and what the result was?

That's assuming they can get their hand on it. It would require access 
to the Flash from the OS level, something that is far from granted.
