    Hi,
    My card reader is not working. It is not recognized in the system profiler and when I enter an SD card, nothing happens. Does anyone in this community know any Terminal level commands where I cand try and turn on my card reader or at least diagnose any problems? I have only updated ram on my Macbook Pro 15' 2.4 ghz mid 2010 and removed the optical drive. I have seen threads where you can turn of the card reader to help minimize battery drainage and I believe I might of had done that a couple of years back. Any help is appreciated :) and thanks. I am running the latest El Capitan Beta 10.11 Beta (15A234d)

    I thinks it's a bug which hasn't fix yet. My USB card reader / external HDD via a hub never works in PB1, 2, and 3 (which works flawlessly in Yosemite).

    Also, there are some other reports about unstable USB devices. So, it seems that Apple still working on this issue.
