[sclug] Enforcing SCSI detection order

I have a whole bunch of USB and Firewire devices, which of course, on Linux 
show up as SCSI devices.

Unfortunately, which device nodes they get mapped to depends on the order in 
which the Linux kernel sees them, which depends on which ones are plugged 
in/switched on.

Is there any way to enforce a particular device, such as my USB floppy drive, 
to get mapped to one particular node, say /dev/sda, so that I know 
that /dev/sda will *always* be the floppy drive or nonexistent if it's not 
plugged in? I haven't reformatted my media drive (/dev/sdb) by accident yet, 
and would rather make sure I don't.

I can't seem to find any information on doing this kind of thing anywhere...
