It might need to be a USB 2.0 hub if it isn't one... Also... not all USB hubs are created equally. As we have discussed before, for other reasons... the USB spec is not firmly defined regarding power... so it is possible to have a "powered" USB hub that does not provide sufficient power to connected devices. As an example... I have an iMac, a powered USB hub, an iPad, and an iPhone. My iPhone will connect via hub or direct to the iMac. My iPad will do the same. BUT... My iPad will only charge when directly connected to the iMac. The iPad will not charge through my powered hub. My iPhone, however, will charge via the hub.
