I've written my module for gamepad that plugged by USB. I've already checked that my installed module detects my device successfully and even calls "probe" method:

 static struct usb_driver driver =

 .name = "Driver#1",
 .id_table = table,
 .probe = probe,
 .disconnect = disconnect,
;

I have also written special urb function, that should "talk" with my device

usb_fill_int_urb(j->irq_in, udev,
 usb_rcvintpipe(udev, ep_irq_in->bEndpointAddress), //!
 j->idata, 32, irq_hh,
 j, ep_irq_in->bInterval); 

But I cannot understand how to initialize action of irq_in. I presume that I need to press something and some information should be written in j->idata. I also did

usb_submit_urb(j->irq_in, GFP_KERNEL);

But nothing happens! Why?
My probe function:

static void irq_hh(struct urb *urb)

 struct devicec *j = urb->context;/*В какую структура из всех процессов дб заполнена после приёма данных???*/
 char *data = j->idata;
 printk(KERN_INFO "irq_hh: %s", data);


static int probe(struct usb_interface *intf, const struct usb_device_id *id)
= URB_NO_TRANSFER_DMA_MAP;

 error = usb_submit_urb(j->irq_in, GFP_KERNEL);

 printk(KERN_INFO "%d",error);

 return 0;
