No, it isn't in /sys/class/power_supply/twl4030_usb
It is in
or equally

The udev rules I have are:

ATTRS{1-0048/twl4030_usb/id}=="floating", ATTR{../../max_current}="500000"
ATTRS{1-0048/twl4030_usb/id}=="102k", ATTR{../../max_current}="851000"

as '102k' is what I get when I plug in my openmoko charger.
