It could be that the ehci driver allocates memory in a different pattern from the uhci driver, or maybe in an illegal fashion. That could explain why your problem only shows up with USB 2.0 but not USB 1.1. At this point, I think I should step aside and let someone who understands the ehci driver take over.
