// Defines for debug verbosity level,
//   i.e., test BULKUSB_KdPrintLevel( n, format....) against these values
//  Example:
//
// BULKUSB_KdPrint( DBGLVL_MEDIUM ,("Entering DriverEntry(), RegistryPath=\n    %ws\n", RegistryPath->Buffer ));
// 
//  The above will print iff gDebugLevel >= DBGLVL_MEDIUM
//
#define DBGLVL_OFF				0		// if gDebugLevel set to this, there is NO debug output	
#define DBGLVL_MINIMUM			1		// minimum verbosity	
#define DBGLVL_DEFAULT			2		// default verbosity level if no registry override
#define DBGLVL_MEDIUM			3		// medium verbosity
#define DBGLVL_HIGH				4		// highest 'safe' level (without severely affecting timing )
#define DBGLVL_MAXIMUM			5		// maximum level, may be dangerous
