Yes, there is also a "weird" behaviour on my Fedora3 as one pen drive is 
recognised as /dev/sda and the other as /dev/sda1 when they are solely 
connected.... It might have to do something with how the pen drives are 
partitiioned. Anyway, try something like:
mount -t vfat /dev/sde1 /mnt/mount_dir

Also it might be helpful to look at the lsusb output. If as root you do:
lsusb to get the bus and device number and then
lsusb -vv -s <yourbus>:<device>

you will get a lot of informaion about the usb device which might be 
helpful...
