I don't think that power is the issue. I did check settings of TPS65217, it returns:
root ~ > i2cget -f -y 0 0x24 0x01 0x3e -> 0 0 1 1 11 10 That means that USB current limit is set to 1300mA (looking at TPS65217 tech reference) I will take look a links you mentioned - hope I will find something Thx.
