High Speed Offload?

I've been working with several sensors connected to the STM32F4-Discovery board using interfaces such as SPI and I2C at rather high data rates.  Well...maybe not that high of data rates, but fast enough where USARTs aren't the ideal method of offload.  Is there some way I can quickly setup an interface (maybe USB?) to offload in real-time data?

''fast enough where USARTs aren't the ideal method of offload''

So how fast is that? To what do you need to ''offload'' - a PC? I know that the FTDI USB-to-UART cables will work fine at 921600 baud:

''Is there some way I can quickly setup an interface...''   Using such a cable is certainly the quickest way to get set up!
