And, this is my card reader that was not recognized:

Of course as I said, not a big deal because the edge has the SD card slot. My Macbook, however, doesn't, so sometimes I forget I can just pop the SD card straight into the edge. I only used it to try to test the USB ports because I didn't have an actual flash drive around to test with. I wouldn't normally use this in the edge.
