  • What kind of port is that ? USB == Universal Serial Bus. Did you mean USB->Parallel adapter ? You'll have to work with USB as long as you're connecting it through USB to your computer. You should check its manual first.

  • USB devices do not have a base address.  The USB device driver creates a "virtual" (software) device that simulates hardware, but does not use the PC bus I/O port address space.

    If you are trying to use a USB device for parallel IO, such as you might do with a built-in printer port -- you have to use a USB device built specifically for this purpose.  You cannot, for example, use a USB printer adapter.

    For what purpose do you want to use the USB device?  I may be able to offer some suggestions.

  • Hi,

    I have the same problem.

    I need to control a simple mechanical device (not a printer or modem) through its control port, which is a parallel port.

    However, my PC is not equipped with parallel ports.

    I have a usb-parallel adapter.

    Any suggestions on hot to send the required control byte to the parallel port through the usb?

    Thank you

      A.
