I don't know if this will help you and I don't have time to research
it further at present, but I remember a utility that was able to
re-write the eeprom in USB devices. I had to use it with some

<br>
I have not used windows for four or five years now, and my memory
is a bit hazy. I don't have these issues with linux!<br>
