STM32F407 USB_hid uygulaması

[Yuunus]

Arkadaşlar merhaba "usbd_hid_core.c" dosyası 4 bytlık veri alışverişi için hazırlanmış ben bunu 64 byte için değiştirmek istiyorum ancak nereye ne yazmam gerekiyor açıkçası anlayamadım; yardımcı olurmusunuz?
...şu an 64 byte veri gönderiyorum ama usb bağlantısında sürekli kopmalar oluyor.
