Given how FTDI does things, I'd be really surprised if this didn't meet
your desires.  Have you actually tried it?  Are you sure there is no
driver in the kernel?

As for your actual needs...  if you want two computers to communicate,
you really ought to be using some sort of networking hardware.  You've
got a computer with a USB port, no serial port, and no ethernet or wifi?
