modification history
--------------------
01f,07may01,wef  changed module number to be (module num << 8) | M_usbHostLib
01e,02may01,wef  changed module number to be M_ + M_usbHostLib
01d,05dec00,wef  moved Module number defs to vwModNum.h - add this
                 to #includes, removed command status codes that lived
		 here and in usbBulkDevLib.h and put into own file in
		 h/usb/usbMassStorage.h 
01c,02sep00,bri  added support for multiple devices.
01b,04aug00,bri  updated as per review.
01a,26jun00,bri  created.
