HELP with Usb Communication

  • Hello ..,

    I have an evaluation board STR750 of ST Microelectronics and I want
    communicate trought Usb port with it.
    On my board there is a firmware to move the mouse of my Macintosh with
    the joystick on it.

    I have tested all Apple examples about usb but I can only see my device
    information but I can't communicate with it because there is an error
    on Open the interface.

    Does anybody help me?
    Is the right thing to do to communicate with a board?

    Thanks,

    Alessandra
  • The USB list would be a far better place to ask this question. It
    doesn't have anything to do with Cocoa.
