AD9912 evaluation board -- Cypress EZ-USB FX2 (68613) - EEPROM missing


I have an AD9912 evaluation board which when connected via USB to the computer shows up as "Cypress EZ-USB FX2 (68613) - EEPROM missing". This board is then not recognized by the AD control software. I have another identical evaluation board with identical configuration which shows up normally first as "AD9549 Firmware Loader" and then as "AD9549 Evaluation Board" when connected via USB and is recognized by the AD control software. I tested it with three different computers always with the same result.

Is the first board broken or is there a way to reflash/initialyze/reset the EEPROM. Jumper JMP2 (Enable EEPROM) is closed on both boards.

Thanks a lot.
