We should only power up the Link after we know it *will* be needed. The way you're doing this is: connect cable -> resume PHY -> resume Link -> if is_charger suspend Link. Where it should be: connect cable -> resume PHY -> if is_charger goto done. Now, to make a generic solution (which is what we want in the long run) we still need a few changes on the OTG support and otg_transceiver on Linux. -- balbi
