FYI, same problem on a known working cable using a SD reader that works on
Windows.
With that reader, I can not read anything. With another reader (SDHC) I can
read
my 32GB cards, but not my 64GB SDXC cards -- using the same cable on the same
port.
I think there is something new in the USB world that my Linux 3.11 kernel
doesn't know about.
