I have a new computer I installed Linux on Red Hat Enterprise Linux ES
release 4 (Nahant), it has one of those all-in-one card readers on it.
I have made mountpoints as root as follows for my thumb, Compact flash
and secure digital drive.
mkdir /mnt/thumb
mkdir /mnt/cf
mkdir /mnt/sd
Now when I tried to mount the Thumb (USB) drive I got an error # mount
/dev/sda2 /mnt/thumb
mount: /dev/sda2 already mounted or /mnt/thumb busy.
So what have I done wrong? I'm thinking sda2 is wrong, but don't know
why?
df -h shows the following
[root localhost mnt]# df -h

You don't tell us anything about your hardware, so any responses really
are largely guesses. From the df output you show above, I'd infer that
sda is a physical hard disk of some type.
The card reader, then, is more likely sdb than sda, so I'd be trying
sdb1 or sdb2 for the thumbdrive. Each possible device will have a
different sdb* value, and figuring oout which is which is largely
guesswork ... unless you're lucky enough to have a kernel with the sort
of USB support for hotplugging that tells you where things connect to
(in my experience, output to the console.
See what "more /proc/scsi/scsi" tells you about what the kernel *thinks*
is connected. Please include this info if you need to post a followup.

This is the last few lines from dmesg. Based on this how would one
mount if I have made the mountpoint of /mnt/thumb
