Bug#784337: usb: [29493.628253] hub 1-0:1.0: unable to enumerate USB device on port 6
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.
