My SD card reader and USB 3.0 Hub have left both answer but see the place in the information system. How can I make them work again?

On my Macbook Pro 13 inch Core I5 2 .6GHz, I just noticed that my SD card reader and USB ports have stopped working. They hub and drive appear in the information of the reporting system. I tried to reset PRAM and SMC but no luck so far and my Time Machine backup is on a SSD in a USB 3.0 hard drive enclosure. Any ideas how to reset the hub and the reader? I'm including all system information in case it is useful
