Try using chainloading it from grub?

Get to the grub boot screen... then hit "c" to put you in the grub command 
shell.. then try following the grub commands for chainloading from the 
USB device, substituting "root (sd0,0)" instead of dh0,0.. 

------------------------------
  1. Set GRUB's root device to the partition by the command
     `rootnoverify' (*note rootnoverify::):

          grub> rootnoverify (hd0,0)

  2. Set the "active" flag in the partition using the command
     `makeactive'(1) (*note Chain-loading-Footnote-1::) (*note
     makeactive::):

          grub> makeactive


  3. Load the boot loader with the command `chainloader' (*note
     chainloader::):

          grub> chainloader +1

     `+1' indicates that GRUB should read one sector from the start of
     the partition. The complete description about this syntax can be
     found in *Note Block list syntax::.

  4. Run the command `boot' (*note boot::).

   However, DOS and Windows have some deficiencies, so you might have to
use more complicated instructions. *Note DOS/Windows::, for more
information.
^^^^^^^^^^^^^^^^^^

Let me know if this works from you.. I've been meaning to try it out..

If not.. There's always booting syslinux off a small CD-ROM or floppy and 
handing off to the USB device.
