I need to know how this code works?

<br />
struct usb_driver {<br />
const char *name;<br />
void * (*probe)(struct usb_device *, unsigned int,<br />
const struct usb_device_id *id_table);<br />
void (*disconnect)(struct usb_device *, void *);<br />
struct list_head driver_list;<br />
struct file_operations *fops;<br />
int minor;<br />
struct semaphore serialize;<br />
int (*ioctl) (struct usb_device *dev, unsigned int code,<br />
void *buf);<br />
const struct usb_device_id *id_table;<br />

struct usb_driver {

const char *name;

void * (*probe)(struct usb_device *, unsigned int,

const struct usb_device_id *id_table);

void (*disconnect)(struct usb_device *, void *);

struct list_head driver_list;

struct file_operations *fops;

int minor;

struct semaphore serialize;

int (*ioctl) (struct usb_device *dev, unsigned int code,

void *buf);

const struct usb_device_id *id_table;

it’s a USB driver structure in linux.

This is simple a structure. What type of help you are looking for?
This is simple structure with some pointer notation. Tell your exact problem.
