Data Structures
struct	uhi_msc_lun_t
	Logical Unit Number (LUN) structure information. More...

Macros
#define	UHI_MSC
	Global define which contains standard UHI API for UHC. More...

Functions
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. More...
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. More...
Functions required by UHC
uhc_enum_status_t	uhi_msc_install (uhc_device_t *dev)
void	uhi_msc_enable (uhc_device_t *dev)
	Enable the interface. More...
void	uhi_msc_uninstall (uhc_device_t *dev)
	Uninstall the interface (if installed). More...
Functions to access at LUNs
uhi_msc_lun_t *	uhi_msc_get_lun_desc (uint8_t lun)
	Gives information about a LUN. More...
bool	uhi_msc_scsi_test_unit_ready (uint8_t lun, uhi_msc_scsi_callback_t callback)
	Checks and update the status of the LUN. More...
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. More...
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. More...
