have you verified that the modules for usb disks are on the initramfs?
(for initramfs-tools, they should be in /etc/initramfs-tools/modules,
for yaird you will have to take a look yourself):
sd_mod
scsi_mod
ehci-hcd
uhci-hcd
usb-storage

to check which modules are actually on the initramfs, do a
zcat /boot/initrd.img-`uname -r`|cpio -t|grep modules
(if you are running a different kernel version then the target, insert
the correct version, of course)

another possibility would also be to increase the timeout how long the
init script waits for the root disk, though i don't know the parameter
atm...

i hope the helps...
