The source of your problem isn't obvious. Here's something you can do to help track it down. Make sure the CONFIG_USB_DEBUG option is set in the configuration and rebuild the uhci-hcd driver. Then load it with: "modprobe uhci-hcd debug=3". Next make sure you have a debugfs filesystem mounted somewhere, and load your driver and wait for those error messages to appear. When they do, navigate to the .../uhci/ subdirectory of the debugfs mountpoint and post a copy of the file corresponding to the host controller that encountered those errors. It should let us pinpoint the trouble.
