/*++

Routine Description:

    This routine is a Co-Installer for the Cyclom-Y Port device.

Arguments:

    InstallFunction - Specifies the device installer function code indicating
        the action being performed.

    DeviceInfoSet - Supplies a handle to the device information set being
        acted upon by this install action.

    DeviceInfoData - Optionally, supplies the address of a device information
        element being acted upon by this install action.

    Context - Points to a coinstaller-specific context structure for this 
        installation request. 

Return Value:

    If this function successfully completed the requested action, the return
        value is NO_ERROR.

    If an error occurred while attempting to perform the requested action, a
        Win32 error code is returned.
