OK - so you need the EEPROM- just don’t tell ASL that you have one. Does that mean that if you buy a DMK URI without the EEPROM you will have a problem? I did pay for the EEPROM in the last one I bought and, because no one told me not to do it, I let ASL write to it and then had to send it back to DMK for a brain-clean. That info really should be on their web page - sheesh.
