Well, could try building the latest FC3 or FC4 kernel under CentOS. I
ran a rebuild generic kernel, then later an FC3 kernel, for a few months
on one machine to get support for a too-new SATA controller until the
RHEL4 kernel caught up.

For some reason that doesn't give anything just after inserting a USB
device, but just the command "dmesg" does.
Can also try (as root):
# tail -f /var/log/messages
then insert card. (Ctrl-C to exit - otherwise runs "forever".)
If something shows up in the output, try
# fdisk -l
and (think I suggested this earlier, but the centosplus kernel man yave
made a difference)
# tail /etc/fstab
and report results. If there is a new entry try mounting it as a user
or as root.

That may be worth a try if other things fail, but the fact that you
could use it under FC4 would tend to indicate a driver rather than a
format problem.
