Serial reads missing last byte

Hi,

I'm using Arduino ver1.8.10 on Win10, board Arduino/Genuino Zero (Native USB Port), ver1.8.3.
I'm using a baudrate of 57600.
I run this program below. When viewing this on the serial monitor in the Arduino IDE, it always reads missing last byte.

`while (Serial.available() > 0) { byte id = Serial.read(); SerialUSB.print(id, HEX); }`

Do you have any suggestions?
Thank you.

Start with the provided Serial.available(), Serial.read(), and SerialUSB.print() sketch on an Arduino/Genuino Zero using the stated IDE, board version, and baud rate. Reproduce the missing-byte behavior and determine whether the final byte is reliably received; the issue is done when serial reads no longer omit it.
