    I have a custom app which is written in C#, and its basic job is to talk to USB port,
    send/receive data from an external device.

    This works fine with Vista but not with win7. Application refuses to launch/crashes soon after.

    Are there any API changes to Win7 which would cause this kind of error?

    I am not a expert in windows programming, just starting up with this assignment to port this app from vista to win7.
