You should notice that the /dev/sd* device(s) for the stick pop into
existence when you shove it in, so the last lettered devices are
probably your stick.  If you see:

 phil at poker:~$ ls /dev/sd*
 /dev/sda  /dev/sda1  /dev/sda2  /dev/sda5  /dev/sdb /dev/sdc /dev/sdc1

with the stick in, it's /dev/sdc.  If the /dev/sd?1 device is not there,
the VFAT partition is direct on the device, otherwise, it's got a
partition table and partition 1 is your VFAT.

You can confirm that by pulling the drive out, and seeing if the disappear.

If you run mount, you may find that the relevant device is already
mounted somewhere, if not, you should be able to mount it by hand with
something like:

  mount /dev/sdc1 /mnt

temproarily, but you'll probably find that RedHat have decided to use
UUIDs or some such, to ensure that the stick always get mounted in the
same place and are perhaps mounting it as /media/Label_Name

Cheers, Phil.
