I have no experience with grub installation on a USB device. I use extlinux
(http://www.syslinux.org/wiki/index.php?title=EXTLINUX) for that. You may use
a minimal extlinux.conf file like
DEFAULT linux
LABEL linux
KERNEL /bzImage
APPEND root=/dev/sdb2
You need to know your rootfs device node in advanced for this to work.
Otherwise you may use "root=UUID=98f012537-7a7c-2213-819e-a69ddf9abc2b"
instead, where the UUID comes from the 'blkid' command output.
Hope this helps,
baruch
