No, since most people who are doing usb booting are using boards with
a "proper" ehci usb controller I've not investigated this further.
Also this only happens after a usb reset, the first time the storage
device works fine, iow this is a corner case. I agree it would be
nice to fix it, but -ENOTIME.
