Ok, probably I solved. From what I see, only the word 0 changes from a chip to another of the same model. Is it right?

Thank you. I am using for transmission the function USBD_CUSTOM_HID_SendReport(&hUsbDeviceFS, ArrayTxUSB, CODA_USB); but without interrupt.Where I should put this function to transmit through interrupt? And how should I enable this interrupt? Which i...

Now I can receive without problems inside the function USBD_StatusTypeDef USBD_LL_PrepareReceive(USBD_HandleTypeDef *pdev, uint8_t ep_addr, uint8_t *pbuf, uint32_t size) called by interrupt. Iside this function I placed my rxusb function that manage...
