What to do when the NUC505 USBD is set to Full-speed mode and the master sends the "SET REPORT" command but the NUC505 is not detected normally? 日期：2018-11-26
When the NUC505 USBD is in Full-speed mode, due to hardware limitations, the master will be unable to be detected normally after sending the "SET REPORT" command. This can be solved by setting the Set Endpoint buffer to increase the length by 4 Bytes.
/* Control endpoint */
USBD_SetEpBufAddr(CEP, CEP_BUF_BASE, CEP_BUF_LEN+4);
