Q: My USB 3.0 Hub and SD Card Reader have both quit responding but show up in System Info. How can I get them to work again?
On my Macbook Pro 13 inch Core I5 2.6 GHZ I have just noticed that my USB ports and the SD Card reader have stopped working. They hub and reader show up in the System Report information. I have tried resetting PRAM and SMC but no luck so far and my Time Machine Backup is on an SSD in a USB 3.0 disk drive case. Any ideas how to reset the hub and reader? I am including all system info in case it helps
