USB 2.0 10-port Hub No Longer Working

My USB 2.0 10-port hub no longer works with any port. When I plug in a USB Flash Drive or card reader nothing is readable in Finder. In some of the ports the light on the flash drive stays lit and on some it goes out after 2-13 seconds. Nothing registers in the finder list of drives.
