Adrian,
        Are you sure on this?  I have definitely seen a lot of things that 
don't work on a USB serial port, and I have heard about a lot of things that 
don't work on a USB parallel adapter.  I can think of no good solid technical 
reason other than bad engineering, cheap manufacturing, or poor driver 
programming, but I would say there are definitely USB serial and parallel ports 
that will not work with some devices.  Regarding usb parallel ports, I also 
know that in shopping for them, many of them specifically say they won't 
support some standard functions or functionalities, or they say they were 
designed for printers and only printers.  That isn't to say that there aren't 
USB serial and parallel ports that would function fully, just that there 
certainly are those that won't.  I suppose it is possible that my experiences 
with serial ports and those I have read about with parallel ports are the fault 
of Windows, but it seems unlikely.
        Dustin

Hi Simon,

There is really no way of doing "non standard" operations with a 
parallel port.
The actual key most likely holds a crypto IC that is going to either 
generate some proprietary codes, or are decrypting/encrypting some 
values passed by by the software. You can take an USB parallel adapter 
and use it like any parallel port. Think of the newer (after year 2000) 
laptops - these don't have a serial port. And post likely the software 
runs on these machines also.

Have phun,
Adrian
