TUSB8042: TUSB8042 : Reprogram the External EEPROM.

Part Number: TUSB8042

Tool/software:

Hi,

I have tryout the TUSB8042 EEPROM Programming Utilities.

Question:  After Flashing the EEPROM, it can no longer be Programmed again.  Is there a OTP mechanism within the 8042 ?

Is there anyway to re-enter into the programming mode again ?

I have tried to trick the 8042 by changing the EEPROM address, but the PC detect as a generic USB Hub with TI VID and PID.

Please help to advice.  Thanks!!

Andrew.
