A USB hub that runs on the power provided though the USB cable (rather than a USB hub powered by an external electrical supply).
Yes. A USB port is supposed to provide a specific amount of power for USB devices. A non-powered hub does not provide the proper power, but is still useful for USB devices that provide their own power (some printers, some cameras), or those that need very little like thumb drives.

A powered USB hub is needed if you have a lot of items to be plugged in and charging. iPods seems to need a powered hub to have enough current to charge fully.

One way is to plug it into the computer via the USB cable. That will charge the battery. But if you plug the USB cable into a USB hub, you will need a powered USB hub to charge the battery. A powered USB hub will have a power adaptor that plugs into the wall. Bypassing the hub and plugging it directly into the computer should always work if the computer is powered up. Also there are some USB chargers that you can plug it into. These accept a USB connection but only supply power. Any USB charger should work, USB is a standard.

In my experience, devices often do this when they are not self powered and are plugged into a usb port which is also not self powered like a non-powered usb hub. The computers usb port puts out a limited amount of power so when the device can't fully power itself windows sees the hardware but can't figure out what it is because it never gets the usb id (or another variant I've had is that it keeps detecting that I've added and removed the device before windows can get a lock on it) Hope that helps
The USB hub has its own power. Some devices use the power from the USB hub and some need more power then they can obtain from the hub. So to answer the original question -is a power hub better- There is no difference over is one better, one device just needs more power then the hub carries so it has to have its own power source.
Connect it directly to your computer or a powered hub with the supplied USB cable.
