Hacking the charger

[myhui]

Has anyone found documentation on how the phone exchanges info with the charger?

If I just do the usual procedure of shorting data- with data+ and leaving ID unconnected, the phone won't charge at the maximum rate.

I connected the five pin USB cable to a break out box and discovered that there is a clock signal on the ID pin and about 0.6 volts DC on the shorted data pins. Also, if I short the ID pin to ground, the phone won't charge at all.

Why not mess with the charger? He's trying to figure out what's special about it, presumably so he can build more at a reasonable price.
