2.If the sent data is more than  one byte, there is no problem when re-sends the data.
3.The retry is done by the hardware, the software does nothing for it.
4.The phenomenon can be reproduced by the attached software and NXP ev board. We change nothing to USBHostLite from LPCWare  except calling the USB_Host_SendControlRequest to send one byte data.
