I have an incomplete idea.

You posted output for two devices, an NEC floppy and a Kingston thumb drive. 
For these two specifically, try the following rules.  I wrapped them by
hand and you may need to unwrap them; I copied the data items verbatim from
your udevinfo output.

  BUS="usb", SYSFS{product}="NEC USB UF000x", NAME="%k",
       SYMLINK="usb-floppy"

  BUS="usb", SYSFS{manufacturer}="KINGSTON     ",
       SYSFS{product}="DATA TRAVELER", NAME="%k", SYMLINK="usbhd%n"

This should put your floppy device at /etc/usb-floppy and one (or more)
Kingston-brand thumb drive(s) at /etc/usbhd0 (and usbhd1, etc.)

It's obviously not a general solution.  My guess is that a general solution
requires using the output of the section containing  DRIVER="usb-storage"
and I don't know nearly enough about something -- almost certainly USB --
to say more.

Since it looks like an interesting problem, I'll look into it further, if
you like.
