It certainly looks like something is wrong either with the interrupt handling or with the controller itself. As another experiment, you can try booting with "noapic". A different experiment would be to rmmod ehci_hcd before plugging in the stick. This will mean the stick only runs at full speed instead of high speed. But if it works at all that will be an improvement.
