Data Structures
struct	uhi_msc_dev_t
	USB MSC device information. More...
Defines
#define	UHI_MSC_NOTIFY_NEW_LUN_EXT
#define	UHI_MSC_SCSI_TIMEOUT   20000
	Timeout on SCSI commands.
Typedefs
typedef void(*	uhi_msc_scsi_sense_callback_t )(void)
	Callback type used by SCSI sense command.
Functions
Routines to initialize the MSC devices
SCSI commands
SCSI protocol sub routines
Interface used by UHC module
USBH_enum_status_t	uhi_msc_install (USBH_device_t *dev)
void	uhi_msc_enable (USBH_device_t *dev)
void	uhi_msc_uninstall (USBH_device_t *dev)
External SCSI commands
bool	uhi_msc_is_available (void)
	Tests if the interface UHI Mass Storage is available The UHI Mass Storage can be busy during the enumeration of a USB Device MSC.
uint8_t	uhi_msc_get_lun (void)
	Gives the number of LUN available Note: A LUN can be available, but with a status LUN_NOT_PRESENT. It is the case for a card reader without card.
uhi_msc_lun_t *	uhi_msc_get_lun_desc (uint8_t lun)
	Gives information about a LUN.
bool	uhi_msc_scsi_test_unit_ready (uint8_t lun, uhi_msc_scsi_callback_t callback)
	Checks and update the status of the LUN.
bool	uhi_msc_scsi_read_10 (uint8_t lun, uint32_t addr, uint8_t *ram, uint8_t nb_sector, uhi_msc_scsi_callback_t callback)
	Reads a LUN data section to RAM buffer Note: The sector size used to define the data section is the sector size returned by LUN in field.
bool	uhi_msc_scsi_write_10 (uint8_t lun, uint32_t addr, const uint8_t *ram, uint8_t nb_sector, uhi_msc_scsi_callback_t callback)
	Writes a RAM buffer in a LUN data section Note: The sector size used to define the data section is the sector size returned by LUN in field.
Internal defines and variables to manage MSC unit
#define	uhi_msc_dev_sel   (&uhi_msc_dev)
	Current USB MSC device selected by the UHI MSC.
#define	uhi_msc_lun_num_sel   uhi_msc_cbw.bCBWLUN
