    ok friends,
    after some hours of Paddle i found that when i initialize usb core it return an error,code of main function is as below:

      int main(void){
  usbStatus stat;

  osKernelInitialize ();                    // initialize CMSIS-RTOS

  // initialize peripherals here

  // create 'thread' functions that start executing,
  // example: tid_name = osThreadCreate (osThread(name), NULL);

  osKernelStart ();                         // start thread execution

        stat = USBD_Initialize(0);
        //now stat is usbThreadError
        if(stat == usbOK)
                stat = USBD_Connect(0);

        while(1)
        {
                osDelay(1000);
        }
}


    as you can see USBD_Initialize function return usbThreadError,now can any one give me some advice to how solve that??
