Note: 1. VID_H/VID_L: high/low byte of VID value
2. PID_H/PID_L: high/low byte of PID value
3. CHKSUM: CHKSUM must equal to VID_H + VID_L + PID_H + PID_L + 1,otherwise
firmware will ignore the EEPROM settings.
4. PORT_NO: port number, value must be 1~4.
5. MaxPower : Describe the maximum power consumption, range=0Ma~500Ma .
Value -> 00H~FAH (unit = 2Ma)
