WhatisthedifferencebetweenUSB2.0andUSB
1.1,andcanIusetheUSBserialhardwarein
USB2.0networks?
TheUSB2.0specificationreplacestheUSB1.1specificationandaddsa
high-speedmodeofoperation(480Mbit/s)tothepreviouslyexistingfull-
speed(12Mbit/s)andlow-speed(1.5Mbit/s)modesofoperation.
BecauseUSB2.0expandsonthefeaturesofUSB1.1whilepreserving
backwarddevicecompatibility,youcanusemostfull-speedandlow-
speeddeviceswitheitherUSB2.0high-speednetworksorUSB1.1full-
speednetworks.
USB-232/485devicesareUSB2.0full-speedcompliant,soyoucanuse
themineitherhigh-speed(USB2.0hubs)orfull-speed(USB1.1hubs)
networks.
