When earlier you said: > It's a > current limiter intended to sit in line with the USB power lines to > ensure the system doesn't go over the maximum current draw (and also > integrates with the power source selection logic the chip has to pick > the best available power source for the system). I assumed that all it did was limit the current to number given. If it also limits the current to ensure that voltage doesn't drop unduly, then I agree with your assertion that it just needs to be told the upper limit. I hope you'll agree that other drivers might need to know the lower limit, so reporting both to all drivers is sensible. Thanks, NeilBrown
