You'll need to make sure USB disk support (usb-storage) is either built
into the kernel or loaded by your initrd.

It's possible to customise what mods the initrd will load.

On a debian system, you can simply edit /etc/initramfs-tools/modules.
Add the modules you want loaded and recreate a new initrd...

mkinitramfs -o /boot/initrd.img-2.6.18-4 2.6.18-4

Substituting your kernel version where appropriate.

HTH,
