R_usb_hstd_SmplRegistration function inusb2_HSMPL_apl.c.

typedef struct {

uint16_t rootport; /* root port */

uint16_t devaddr; /* Device address */

uint16_t devstate; /* Device satate */

uint16_t ifclass; /* Interface Class */

uint16_t *tpl; /* Target Peripheral List */

uint16_t *pipetbl ; /* Pipe Define Table address */

USBC_CB_INFO_t classinit; /* Driver init */

USBC_CB_CHECK_t classcheck; /* Driver check */

USBC_CB_INFO_t devconfig; /* Device configuered */

USBC_CB_INFO_t devdetach; /* Device detach */

USBC_CB_INFO_t devsuspend; /* Device suspend */

USBC_CB_INFO_t devresume; /* Device resume */

USBC_CB_INFO_t overcurrent; /* Device over current */

}USBC_HCDREG_t;
