Personally I'd use an AVR to drive it & forward stuff to its UART.  Or  
the Obdev USB stack for AVR -- check out the USBasp programmer, that  
is effectively a "USB to SPI" adapter.  I'm using that USB software a  
fair bit as I don't have a computer with a real UART (non-USB I mean)  
anymore...  progress, eh.
