You are apparently using a SCSI device, so I assume it is a USB
based card reader, not a directly attached SD/MMC reader.

My guess is that the problem is the way that the card is presented
to the USB mass storage driver by the reader. Generally, there is
no problem with 2GB SD cards, so it would be good if you can try
a different card reader with your cards.

Also, please supply the "lsusb -v" output for the card reader.
