On the SoCKit, using this cable the "dwc_otg_core_host_init: Timeout!" messages no longer appear. A few of the USB sticks I have here are immediately recognized and function normally - a first for me with the latest version of u-boot. For others, like the Kingston SE9 stick, I get the same result as you - it's not detected at all. I have yet to find one of the non-working USB sticks on the SoCKit fail with the same sort of long timeout followed by the zombie behavior exhibited by the DE0/Kingston combination.
