使用Device IO Control 讀寫 USB Mass Storage

http://www.ezblog.idv.tw/Download/USBStorage.rar

這是一個不透過檔案系統,去讀寫USB Mass Storage 任何位置(包含FAT)的方式

首先需安裝微軟的DDK並include "usbioctl.h" , "usbdi.h" , "ntddscsi.h"

有幾個資料結構要定義

typedef struct _SCSI_Device_Info_

{

  SCSI_PASS_THROUGH Spt;

  BYTE Sense[  ];

  BYTE Data[  ];

} SCSI_Device_Info, *pSCSI_Device_Info;

typedef struct _SCSI_PASS_THROUGH_WITH_BUFFERS

{

  SCSI_PASS_THROUGH Spt;

  ULONG Filler;      // realign buffers to double word boundary

  UCHAR ucSenseBuf[ SPT_SENSE_LENGTH ];

  UCHAR ucDataBuf[ SPTWB_DATA_LENGTH ];

} SCSI_PASS_THROUGH_WITH_BUFFERS, *pSCSI_PASS_THROUGH_WITH_BUFFERS;

typedef struct _SCSI_PASS_THROUGH_DIRECT_WITH_BUFFER

{

  SCSI_PASS_THROUGH_DIRECT sptd;

  ULONG Filler;      // realign buffer to double word boundary

  UCHAR ucSenseBuf[ SPT_SENSE_LENGTH ];

} SCSI_PASS_THROUGH_DIRECT_WITH_BUFFER, *pSCSI_PASS_THROUGH_DIRECT_WITH_BUFFER;
