Yes I didn't go look but I talked with Balaji about the adapter path and
I know he addressed it, so a new power_supply guy turning up called
"adapter" will be this I think.

cat /sys/class/i2c-adapter/i2c-0/0-0073/pcf50633-mbc/usb_curlim

should be enough hopefully -->

0     - no power on USB
100   - not enumerated (or currently, buggy enumeration)
500   - enumerated
1000  - AC Charger
