Soren,
I don't know about the USB parallel port converters but there are
variousways you can add USB connectivity yourself.
A simple way are the USB devices from FTDI
(http://www.ftdichip.com/FTProducts.htm)
Either the FT232R or the FT245R. These are both single chip solutions
that provide a USB interface on one side and an 8 bit bi-directional fifo
on other. The 232 is mapped as a serial port at the system level, whilst
the 245 is higher bandwidth and accessed through an API (use ctypes etc.)
Windows, Linux & Mac OS X are supported.
FTDI provide evaluation modules (tiny, USB powered) that you can be up and
running with in no time:

Good luck!
