Timeout's typically are caused by IRQ routing problems. What's PCI device 00:09.0? -84 is -EILSEQ which is CRC/Timeout. That's usually caused by a flaky device or flaky cable. I'd suggest checking out the cable, perhaps swapping it with another one if possible. You may also want to try to the uhci.o driver, but I suspect this isn't a host software problem.
