bypluggingdirectlyorthoughaUSBcable;
1.1 IfyourUSBMSCstoragedeviceis2.5”USBharddiskandwithoutadditionalpower
supplyunit,youmayconnectanadditional5VDCpowersupplytoJP10ofDXevaluation
boardthenturnonSW2.Itcanhelpresolvepossibleinsufficientpowerproblemofthe
2.5”USBharddisk.Notethat5VDCpowersupplyunitaddressesusuallyseen
insufficientpowerissuewithusinga2.5”USBharddrive.Itisnotrequiredwithother
USBthumbdrives.
