Forever loop. usbInterruptIsReady3() usbSetInterrupt3()

Forever loop. usbInterruptIsReady3() usbSetInterrupt3()
(sorry for my English, it is not native language)

Hi, I make some explain:
I want make joystick project with two virtual devices, and send reports:
a) Virtual_Joystick#1 -> Report#1 -> EP81
b) Virtual_Joystick#2 -> Report#2 -> EP82
Every joystick must be do 125 reports at second (with USB_CFG_INTR_POLL_INTERVAL=10)

First.
I make simple project( based on "hid-mouse") change HID Discriptor:

PROGMEM const char usbHidReportDescriptor[96] = { /* USB report descriptor, size must match usbconfig.h */
    0x05, 0x01,                    // USAGE_PAGE (Generic Desktop)
    0x09, 0x05,                    // USAGE (Game Pad)
    0xa1, 0x01,                    // COLLECTION (Application)
    0xa1, 0x00,                    //   COLLECTION (Physical)
    0x85, 0x01,                    //     REPORT_ID (1)
    0x05, 0x09,                    //     USAGE_PAGE (Button)
    0x19, 0x01,                    //     USAGE_MINIMUM (Button 1)
    0x29, 0x10,                    //     USAGE_MAXIMUM (Button 16)
    0x15, 0x00,                    //     LOGICAL_MINIMUM (0)
    0x25, 0x01,                    //     LOGICAL_MAXIMUM (1)
    0x95, 0x10,                    //     REPORT_COUNT (16)
    0x75, 0x01,                    //     REPORT_SIZE (1)
    0x81, 0x02,                    //     INPUT (Data,Var,Abs)
    0x05, 0x01,                    //     USAGE_PAGE (Generic Desktop)
    0x09, 0x30,                    //     USAGE (X)
    0x09, 0x31,                    //     USAGE (Y)
    0x09, 0x32,                    //     USAGE (Z)
    0x09, 0x33,                    //     USAGE (Rx)
    0x15, 0x81,                    //     LOGICAL_MINIMUM (-127)
    0x25, 0x7f,                    //     LOGICAL_MAXIMUM (127)
    0x75, 0x08,                    //     REPORT_SIZE (8)
    0x95, 0x04,                    //     REPORT_COUNT (4)
    0x81, 0x02,                    //     INPUT (Data,Var,Abs)
    0xc0,                          //   END_COLLECTION
    0xc0,                          // END_COLLECTION
   
    0x05, 0x01,                    // USAGE_PAGE (Generic Desktop)
    0x09, 0x05,                    // USAGE (Game Pad)
    0xa1, 0x01,                    // COLLECTION (Application)
    0xa1, 0x00,                    //   COLLECTION (Physical)
    0x85, 0x02,                    //     REPORT_ID (2)
    0x05, 0x09,                    //     USAGE_PAGE (Button)
    0x19, 0x01,                    //     USAGE_MINIMUM (Button 1)
    0x29, 0x10,                    //     USAGE_MAXIMUM (Button 16)
    0x15, 0x00,                    //     LOGICAL_MINIMUM (0)
    0x25, 0x01,                    //     LOGICAL_MAXIMUM (1)
    0x95, 0x10,                    //     REPORT_COUNT (16)
    0x75, 0x01,                    //     REPORT_SIZE (1)
    0x81, 0x02,                    //     INPUT (Data,Var,Abs)
    0x05, 0x01,                    //     USAGE_PAGE (Generic Desktop)
    0x09, 0x30,                    //     USAGE (X)
    0x09, 0x31,                    //     USAGE (Y)
    0x09, 0x32,                    //     USAGE (Z)
    0x09, 0x33,                    //     USAGE (Rx)
    0x15, 0x81,                    //     LOGICAL_MINIMUM (-127)
    0x25, 0x7f,                    //     LOGICAL_MAXIMUM (127)
    0x75, 0x08,                    //     REPORT_SIZE (8)
    0x95, 0x04,                    //     REPORT_COUNT (4)
    0x81, 0x02,                    //     INPUT (Data,Var,Abs)
    0xc0,                          //     END_COLLECTION
    0xc0                           // END_COLLECTION
};

and send Report#1 and Report#2 with ONE EndPoint#81. it is works fine.

Windows asking reports, and MC send Report#1 and Report#2 step by step.

Second.
I change "usbconfig.h"

#define USB_CFG_HAVE_INTRIN_ENDPOINT3   1
#define USB_CFG_EP3_NUMBER              2

add new function at "main.c"

void usbSendHidReport3(uchar * data, uchar len)
{
   while(1)
   {   DBG1(0x05, 0, 0);   /* debug output: interrupt report prepared */
      wdt_reset(); usbPoll();
      if (usbInterruptIsReady3())
      {
         DBG1(0x06, 0, 0);   /* debug output: interrupt report prepared */
         usbSetInterrupt3(data, len);
         break;
      }
   }
}

and try to send: Report#1 with EndPoint#81, Report#2 with EndPoint#82

usbSendHidReport((void *)&gamepad_report_1, sizeof(gamepad_report_1));
usbSendHidReport3((void *)&gamepad_report_2, sizeof(gamepad_report_2));            

and... here some troubles:
a) Windows never asking for paket EndPoint#82, but HID Discriptor working great (windows create 2 pipes)

b) MC make a forever loop at checking "usbInterruptIsReady3()"
