    I've owned a powered USB 2.0 hub for several years now, and plug my iPhone in to charge or sync it with my computer. Sometimes when it just sits on its own, and charges, a message pops up on the phone telling me that this device is not supported. Is there some way to fix this, or should I buy a supported USB hub instead? Any of them designed to work correctly with the iPhone? I'd rather not get a multi port charger, because a USB hub is of more use to me...

    What else is connected to the hub? If the hub is running low on power the iPhone will not get the power it expects and will complain. There is no way of fixing this as far as I know, you need a better hub.

    Most hubs work that have a separate power supply of at least 0.5 A per port. A USB 3 hub, even if you don't have USB 3, has a higher power per port design so you have a higher power budget for the hub. Also, there a special hubs designed with a high power port so that you can change and sync a phone/tablet.

    At the moment the only thing that's connected is the iPhone. I've had two external hd's connected to it in the past, and it had no problem powering them. The hub has its own power supply, and the iPhone's cable is the original from Apple.

    I guess I'll start searching for a different one.

    Maybe the external HDs damaged the hub by drawing too much current. I agree with the other suggestions to try a different hub.
