I've never tried that, but does grub recognize the usb drive at all?
You may need 'insmod usb.mod'. The first step is to go to the grub
command line and get it to recognize the usb drive. Then get it to boot
from the command line. Only after you can do that, try to get grub.cfg
right.
I suspect that from grub's perspective, after the bios hands off to the
usb drive, that root is hd0.
