    CY7C65640 and blank 25LC040

      Hi,

         

      In my design I have CY7C65640-LTXC and EEPROM 25LC040-ISN. Is it a MUST to load EEPROM with at least default configuration 0xD0 Load, or will the USB hub run correctly when EEPROM blank? How would I go on about programming this EEPROM?

         

      On power up sometimes (1 in 15 time) CY7C65640-LTXC is stuck and the hub is not operating properly (it does not recover after chip reset, only on power up), could this be because EEPROM is blank?

         

      Thank you.

         

       

         

      Regards,
