Basically I want to use the USB port as a high speed serial port.
Me and a friend of my want to play with a radio transmitter(and
of course a receiver) that takes an 1.5 Mbit/s input stream and
sends it out in the air.

As of yet I don't know about the voltage level and such, maybe I can't
use the USB port, but as this is a hobby project we don't want to buy
new hardware, and the USB port is the only interface on my computer that
can send data fast enough(and the only interface on my computer that I
have no knowledge about :)

Thanks for Your answer! The reason I'm asking in this list is that I'm doing
most of my developing in Linux :)
I think I'm going to do some more research before I'll terrorize this list
again ;-)
Thanks!
