Software Environment:
Problem Description:
I have two card readers, SanDisk ImageMate  CF-SM and Neodio ND5010. Both
exhibit the problem of not registering and then not allowing to mount flash
cards larger than 32MB. I have three of these cards, 32M (fat), 64 and 256M
(vfat). I am not really sure if this is SCSI, USB, or a fs (fat vs. vfat) issue.

Steps to reproduce:
Put a card in a reader and hook it up to the USB. If 32MB card is in it (can
also be inserted later) it works. Attempts with 64M and 256M cards fail. Tried
other kernels too (2.6.11), without success. Used to work before I exchanged my
motherboard, will provide additional info on request.
