This is actually kind of broken in that the devices are enumerated
twice: first through the OHCI, then through the EHCI. Still, the
usb-storage driver binds to them both.

Here the USB mass storage driver is loaded as expected but for some
reason it doesn't bind to the storage device that was already found;
only to the next device found.
The working config has:
# CONFIG_USB_STORAGE_CYPRESS_ATACB is not set
whereas our config has:
CONFIG_USB_STORAGE_CYPRESS_ATACB=m
Maybe the main usb-storage driver is ignoring this device because it
should be handled by the ums-cypress sub-driver, but that is missing
from the initramfs.
Can you try this:
1. Add 'ums-cypress' to /etc/modules
2. Run 'update-initramfs -u 2.6.30-1-686' (or any kernel version that
shows this problem)
3. Reboot into that kernel
?
