USB backend question

Hi, all.

If I need to make my custom USB backend,
should I use IOKit to communicate with USB printers?

Reading a source code of USB backend of original CUPS,
it uses device files to connect to printers.
(/dev/unlpt?, /dev/ulpt? etc... depending on the kind of OS.)
However, I can't find such device files for USB devices on Jaguar.
Does CUPS on Jaguar use device files of different name from UNIX,
or does it use IOKit to communicate with printers?
