Routine Description:

    Debug Print function.

    Prints based on the value of the HidIrDEBUG_TRACE_LEVEL

    Also if HidIrW98_Debug_Trace is set then all debug messages
    with a level greater than one are modified to go in to the
    ntkern trace buffer.

    It is only valid to set HidIrW98_Debug_Trace on Win9x
    becuse the static data segments for drivers are marked read-only
    by the NT OS.

Arguments:

Return Value:
