That's interesting; I thought the issue was that Motorola chargers have the RX and TX lines connected together, or something like that, so the phone can detect that a dumb charger is connected (as opposed to a hub that can't deliver 500mA). Are you sure you are getting 500mA from it? Then either yours must be a smart charger after all (the phone can talk to it and get permission to go into fast_cccv mode) or something has been fixed that I didn't know about... My theory was that if the USB lines could also be used in GPIO mode, then you can detect a dumb charger with a little bit-banging. I bet that's what the Moto phones do (guessing). > I don't know about a car charger (I have dis-selected having a car :-) > so I can't advice you about that. Motorola makes those too, but they are also dumb chargers (just a regulator supplying 5V).
