Proposals on how to do this would be gladly reviewed.

But again, please remember that these USB devices are really SCSI
devices.  Same for SATA devices.  There is a reason they are using the
SCSI layer, and it isn't just because the developers felt like it :)

Use mount-by-label instead, it's much saner and handles device name
movement just fine (as does the UUID method that you seem to hate.)
Look in /dev/disk/ for a wide range of options that you have in which to
choose how to pick your block devices.

Oh, and this seems like a very Ubuntu specific rant, might I suggest you
contact the Ubuntu developers about this?  The kernel doesn't dictate
that the distro has to use these long identifiers, and there is nothing
we can do about it.

good luck,
