For what it's worth, Ravman, I agree with the others. I've never heard of anyone having problems with their iPhones charging off USB once the phone is locked. I agree that USB is low power unless you're using a powered hub, so it is slow to charge. But my phone charges fine hub or not with when it's locked.
Maybe there's something wrong with your system?
