打印测试num_bytes字节实际是72B,比后面结构体大所以报警，应该是USB setup 返回的描述信息吧
这个应该如何解决？
原来USB 4G测试没问题的。

如果屏掉以上两条，连接没有问题。有数据流时
E (56664) ESP_USBH: D:/PROJECT/ESP32/esp-iot-solution/components/usb/esp_usbh/esp_usbh.c:711 (esp_usbh_urb_enqueue):invalid usb state

实际获取到的描述符，大于了预期，所以报错。可能这个模块的向下兼容有点问题？

传输有问题，可能端点地址配置不正确。需要先把描述符打出来，查一下正确的端点地址
