mounting a USB drive

[Glenn at home]

I have a USB 20GB drive which is really my RockBox JukeBox (Archos), and I 
want to mount it using Knoppix with my Debian system.
It is essentially a USB 20GB 2.5 inch hard drive with a FAT32 file system.
I did try typing mount, and also the DF command, and it seems, from what I 
read,  that I would use:
mount /dev/pts
and it wants to know the file system.
All that I can see in mount is usbfs.
Does Linux see FAT32 as fat32?  Or do I use some other terminology for this 
kind of FS?
Thanks
