I never fixed this due to the lack of interest for cramfs. That said, your setup seems a bit crazy. What is inside your cramfs? The kernel? You should rather put your kernel into a plain partition on the USB disk. Or do you only have your rootfs inside the cramfs? I rather recommend ext2 or ext3 for this.
