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)
6. DEVICE REMOVALBE:
-

-
0: Device attached to this port is removable.
1: Device attached to this port is non-removable.
7. VENDOR LENGTH: offset 10h contains the length of the vendor string. Values of vendor string is
contained from 11h~3Fh.
8. PRODUCT LENGTH: offset 40h contains the length of product string. Values of product string is
contained from 41h~6Fh.
9. SERIAL NUMBER LENGTH: offset 70h contains the value of serial number string. Values of serial
number string is contained after offset 71h.
