No. The Windows world presents a standard SERIAL DRIVER interface, at
least that's the theory that is preached. I see no reason why a USB
serial port wouldn't do the same. USB defines a serial port
interface, IIRC, which is the same across manufacturers (in theory)
which would be handled by a single USB driver in our USB stack.
Likewise with parallel ports. Although turning a USB parallel port
into a bit twiddling interface may present some interesting
challanges.
