Sprint U300 4G/WiMax USB card - can it be made to work with OS X (Leopard)?

It seems that Sprint do not provide drivers for this USB adapter. Is there a way to make this work with Apple OS X, so that I can use it with my MacBook Pro? It appears to have USB storage and this is all that works for me.
