Why doesn't my Droid phone charge when connected to a powered USB hub that is not connected to my computer?

I notice that my new Motorola Droid phone charges perfectly fine when I connect it to my computer via the USB cable, or if I connect it to a car cigarette lighter->USB adapter, or a wall power->USB adapter. It also works fine when I connect it to a powered USB hub that is connected to my computer.

However, if that same powered USB hub is not connected to my computer when I connect the phone, it does not charge. If I connect the computer to the hub, and then connect the phone to the hub, it will charge. If I then disconnect the computer from the hub, the phone will continue to charge.

Does anyone know why this is happening, or what I can do to be able to charge my phone from a powered hub, without my computer being present?
