Probably should have been addressed to the list... Ah, and thanks by the way :) /jOERG

It is maybe a good idea to limit the current from the ID pin with a resistor (e.g. 330 Ohm) or add a pulldown resistor to it to protect the ADC (see attachment)? > Now if we detect there's not 0volt but instead there's 5volt on the ID-pin > while we're applying 0volt to internal R, we got a new info about what's > plugged to our USB-receptacle, and we might ->>route this 5volt to our > PMU<<-. > Got the picture? I had to read your mail twice before I got it. I think your idea is genious:) Very simple HW solution to this complicated problem. -- Please don't send me Word or PowerPoint attachments.
