Can I force USB drives' device name?

Hi, list!

I've got two USB storage devices here, a Jump Drive and a floppy/superdisk
drive. When plugged in by itself, the floppy drive becomes /dev/sda; the
Jump Drive becomes /dev/sda1. When they are both plugged in together,
whichever one was plugged in first gets /dev/sda(1), and the other
becomes /dev/sdb(1). This behavior is expected and understood.

What I'd like to know is whether or not it's possible to make the floppy
drive, for example, *always* /dev/sdb, even if it's plugged in by itself.
This would simplify life by allowing me to have /etc/fstab always know where
the floppy drive is, make desktop icons, etc.

Does anyone know how to do this?

With suitable udev rules, you can name them anything you like, say /dev/
floppy and /dev/jumpdisk. See http://www.gentoo.org/doc/en/udev-guide.xml
and http://www.reactivated.net/udevrules.php

That looks like exactly what I was hoping for. Thanks!
