Any suggestions?
Those errors arise because your system loads uhci-hcd before ehci-hcd. You can change the load order to get rid of the errors, or you can just ignore them. Here's what happens. When uhci-hcd loads, the USB core sees your high-speed hub and begins to initialize it. A few moments later ehci-hcd loads, and it switches the port connection away from the UHCI controller over to the EHCI controller. As a result uhci-hcd isn't able to communicate with the hub any more -- that's what the error messages are reporting. But ehci-hcd is able to communicate with it perfectly well.
