/dev/mmcblk0 USB device equivalent on Fedora 18

[Aaron Gray]

Hi,

I am trying to follow some instructions that say do a :-

    'xzcat image.img >/dev/mmcblk0'

to a USB SD card reader. But '/dev/mmcblk0' does not exist.

I have tried usbmon0/1/2/3 but am just getting write errors.

Many thanks in advance,

Aaron
