    Parallel Port to USB controller and outb()

    Hi guys,

    From what I've tried and read I can't use outb() or inb() to control a parallel port (which connects via usb).

    Any body know how to control a parallel port for systems without a physical parallel port connector (and hence have to buy and use a parallel port to usb converter).

    Thx in advance.

    In what way do you want to control the port? Is the port already registered and usable via the kernel and devfs?

    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
