Hi,
This is just for info.I have a Kingston 8GB class 4 SDHC card. When I try to write to the card under windows 7 or linux the device dissappears. In linux the dmesg output is:

The iso stick is brand new with the latest firmware. Writes work with a 1GB micro SD card and I've seen one ISO file load. I have a class 10 32GB card coming this week so hopefully it will work better with that.
